New USB Type-C Data Line Protection IC Provides Industry’s Fastest Response Time at 15 Nanoseconds

San Jose, Calif.  April 19, 2018   Power management leader Kinetic Technologies announced today the launch of USB Type-C Port Protector KTU1101, an important milestone for USB data line protection, and a significant addition to the company’s extensive overvoltage protection (OVP) portfolio. Now designers can avoid risk with this new, ultra-fast technology that offers an OVP response time of 15 nanoseconds (ns) beating the industry by a large margin.

Our goal is to raise the bar across OVP technology, and the KTU1101 does just that,” says Kinetic Technologies Vice President David Nam. “This level of protection for USB Type-C ports is an industry first. Competitive solutions are more than 350% slower to respond, which results in risk of system failure during short-to-VBUS events.” He continues, “this is a superior OVP solution that meets the demands of major OEMs, including the ability to truly protect down-stream ICs with a 6V absolute maximum ratingno one else is doing this.”

The KTU1101 provides ESD, surge, and OVP for USB Type-C CC/VCONN and SBU signal lines. Physical or moisture-related shorts between the signal pins and VBUS at elevated PD voltage levels can cause catastrophic damage to internal electronics; KTU1101 avoids the risk by keeping internal data line voltages below 6V. Integrated ESD protection eliminates the need for external TVS diodes.

The KTU1101’s ultra-fast response time and small solution size make it an ideal solution for USB Type-C port protection across many applications, including mobile and computing devices like smartphones, tablets and computers, as well as industrial hardware and enterprise solutions.

The KTU1101 is packaged in RoHS and green compliant 1.7mm x 2.1mm wafer-level chip-scale packaging and samples are available today. Contact Kinetic Technologies for more information.

Kinetic Technologies Releases Dual Channel Camera Flash Driver ICs, with Independent LED Control

San Jose, Calif.   December 16, 2016 – Kinetic Technologies, a high-performance analog and mixed-signal semiconductor company focused on developing power management solutions for computing, consumer, industrial, and communications markets, today introduced the KTD2688 and KTD2688A, both dual channel, high current LED Flash driver ICs, with independent channel control.  The KTD2688 and KTD2688A are specifically designed for driving high current, camera flash, LEDs used today in mid-to-high end Smartphones.

The KTD2688 and KTD2688A are the ideal power solution for high-power flash LEDs. Integrating a synchronous boost converter and two current sources, plus extremely flexible programming via I2C control, the KTD2688 and KTD2688A provide a very small total solution for use in feature rich Smartphones. To compliment the I2C interface, the KTD2688/88A also features hardware STROBE/TORCH pins for maximum control flexibility. The two integrated current sources are independently controlled, with both their on and off state, and current settings in either of three functioning Flash/Torch/IR modes can be programmed independently by the I2C interface. To conserve battery life when the Camera module is not in use, there is a HW enable pin that powers the KTD2688/88A down reducing the standby power.

In addition to the flexible control, the KTD2688 and KTD2688A have integrated many protection features, to prevent damage to the IC, the LEDs or the surrounding environment. These include, three programmable low voltage input protection modes to can prevent a system reset, when the LED Flash is initiated, if the battery is in a discharged state. Cycle-by-cycle input current limit protection, output over-voltage protection, LED fault (open or short) protection, flash timeout protection and thermal shutdown protection are also included.

High definition cameras have now become common place in today۪s mid-to-high-end Smartphones.” said Erik Ogren, Senior Director of Marketing at Kinetic Technologies, in a quest to differentiate their products in the marketplace, manufacturers are continually seeking to not only improve the image sensors and optics, but also the flash solution itself. “Today manufacturers use a variety of solutions consisting of multiple LED (up to four), in either all white or amber and white combinations. All these solutions require proprietary control algorithms to provide the best quality photograph without washing out the subject matter. To achieve this, precise independent control of the LEDs is required. The KTD2688 and KTD2688A, provide the necessary control to each channel providing 128 steps of LED current, whilst also shaping the rising and falling edges.”

The KTD2688 provides a maximum flash current of up to 1.5A per channel and up to 187.5mA in Torch mode. In Flash mode, the programmable safety timer has a timeout range of 10ms to 400ms. The KTD2688A features the same maximum flash current of 1.5A, but increases the Torch current to a maximum of 375mA and the safety timer range of 40ms to 1600ms.

The KTD2688/88A is supplied in a WLCSP-12, 1.3 x 1.57mm, RoHS and Green Compliant packages and are rated over the -40 degree C to +85 degree C temperature range.

Kinetic Technologies Releases Two Low-Resistance, Reverse-blocking, Slew-rate Controlled, Power Saving Load Switches

San Jose, Calif. November 5, 2016 – Kinetic Technologies, a high-performance analog and mixed-signal semiconductor company focused on developing power management solutions for computing, consumer, industrial, and communications markets, today introduced the KTS1601 and KTS1605, reverse-blocking, slew-rate controlled load switches with extremely low on-resistance.  The KTS1601 and KTS1605 are ideal for use in single cell Lithium-ion battery-based equipment, including mobile phones, Smartphones, Tablets, wearables and other portable devices or any appliance operated from a fixed 3.3V or 5V supply, such as HDD or SSD.

The KTS1601 and KTS1605 are the first generation of slew-rate controlled load switches products from Kinetic, significantly improving the efficiency in battery powered electronics.  The KTS1601 and KTS1605 power saving load switches are inserted between the battery or supply voltage and a load, and only turned on when the load is required by the system, thereby minimizing the power drain. The KTS1601 and KTS1605 features a controlled soft-on slew rate of typical 2.7ms that limits the inrush current for designs with heavy capacitive loads and minimizes any resulting voltage droop at the power rails.

With an operating voltage range from 1.5V to 5.5V, the KTS1601 and KTS1605 features the lowest on-resistance, and quiescent current of any similar packaged device on the market today. At an input voltage of 3.3V, the KTS1601 and KTS1605 features 24m and 13.4m respectively, providing a low IN to OUT voltage drop, maximising the voltage to the load. Both products are reverse-blocking when OFF, ensuring there are no discharge paths from OUT to IN, should a load be powered from a dual supply. The KTS1601 can operate up to a continuous current of 2A and the KTS1605, 5A.

With more and more functions being added to portable products, the battery capacity is struggling to meet the consumers expected operating time,” said Phil Dewsbury, Senior Director of Product Marketing at Kinetic Technologies. “With operating currents of these functions approaching their minimum, designers must look elsewhere to extend the battery life. The KTS1601 and KTS1605 load switches, provide an additional means to save power, by shutting down, un-used functions in a Smartphone or other portable product, without compromising the reliability or operating parameters of the system.”

The KTS1601 and KTS1605 also features an internal pull-down resistor on the enable pin to ensure the device remains off, should the input enable be allowed to float. The KTS1601 and KTS1605 also have an active pull-down option, that is connected between the output and ground, to discharge any residual load voltage at the output, when the switch is off.

Both devices include over-temperature protection, and ESD compliance at the input to IEC61000-4-2 level 4 of 8kV Contact Discharge and 15kV Air Discharge and are rated over the -40 degree C to +85 degree C temperature range. The KTS1601 is supplied in a WLCSP-4, 1.0 x 1.0mm, while the KTS1605 is supplied in a WLCSP-6, 1.0mm x 1.5mm, both RoHS and Green Compliant packages.

Key Features of KTS1601/1605

  • Operating Range: 1.5V~5.5V
  • Low RDS(ON) MOSFET:
    • KTS1601 Typically 24m @ 3.3V

Kinetic Technologies Releases Two Surge Protected, Single Input, Dual Output Load Switches with OVP

San Jose, Calif. September 5, 2016 – Kinetic Technologies, a high-performance analog and mixed-signal semiconductor company focused on developing power management solutions for computing, consumer, industrial, and communications markets, today introduced the KTS1678 and KTS1679-1, both single input, dual output, surge protected, load switches with selectable OVP.  The KTS1678 and KTS1679-1 are specifically designed for routing VBUS power to provide alternative functions in mid-to-high end Smartphones or Tablets.

Both the KTS1678 and KTS1679-1 consist of two very low resistance power switches configured as single input, dual output, change-over switch. The input to both switches is protected against VBUS surge voltages of up to 100V, and is also protected against over-voltage, on both the VBUS to OUT and VBUS to SYS paths, providing protection to downstream components from abnormal input conditions. The main switch (VBUS to OUT) features a unidirectional, 23m, active-LOW enabled 3.5A rated MOSFET, while the secondary switch (VBUS to SYS) is a reverse-blocking, 30m, active-HIGH enabled, 6.0A rated MOSFET. Both input switches are rated up to a maximum of 28V. The KTS1678 has a fixed OVP trip point of 13.9V 400mV for the VBUS to OUT switch, with an OVP trip point of 5.25V 250mV for VBUS to SYS switch. The KTS1679-1, replaces the SHDN pin (used to conserve power) with a SEL pin, giving the user the option to either select the VBUS to OUT OVP trip point to 10.4V 300mV by allowing the SEL pin to float or to 5.8V 200mV by tying the SEL pin to GND. This allows compatibility with many of the fast charging schemes, that use higher charging voltages. The VBUS to BAT OVP remains fixed at 5.8V 400mV.

When VBUS is greater than 2.7V, the KTS1678 POK LDO provides an always ON power source, regardless of the OVLO, EN1 and EN2 state, to power downstream components permitting operation without an installed battery.  In the KTS1679, the POK LDO is replaced by a battery voltage sense function (SNS), that switches off the charging current to the battery, if the battery voltage exceeds its maximum rating.

The introduction of the Type-C USB connector has provided Smartphone manufacturers with both an opportunity and a challenge said Phil Dewsbury, Senior Director of Product Marketing at Kinetic Technologies, while the Type-C connector offers the ability to handle a higher charging current, those manufacturers previously using an un-committed pin on the Micro-USB connector for test purposes, have to look for an alternative solution. The KTS1678 offers those manufacturers the opportunity to use the VBUS pin to directly route the tester to the system board, bypassing the integrated battery charger. Alternatively, the KTS1679-1 allows manufacturers using high current, direct charging adapters to directly access the battery terminals, safe in the knowledge that any over-charge will be detected by the integrated OVP circuitry.

The KTS1678 and KTS1679-1 are supplied in a WLCSP-28, 2.96 x 1.67mm, RoHS and Green Compliant packages and are rated over the -40 degree C to +85 degree C temperature range.
