This product is shortly to be EOL’d and is therefore not recommended for new designs. Existing customers should contact their local sales office for more information.
Kinetic Technologies recommends the KTS1697A for all new designs.
7ARMS VBUS Current-Sink Protection Load Switch
Description
The KTS1696A is a low-resistance, high-current load switch with soft-start, over-voltage protection, “ideal diode” reverse-current protection, short-circuit protection, over-current protection, over-temperature protection, and integrated TVS. It is optimized to protect systems with USB Type-C PD ports and barrel connectors that sink up to 140W at 20V and must withstand up to 29V on VBUS.
Automatic reverse-current protection acts as an “ideal diode” and isolates VBUS when charging or powering the system via another port, regardless of the enable status. Soft-start limits inrush current when turning on with large capacitors at the output. The integrated TVS provides IEC industry standard ESD and ±90V surge ratings.
The KTS1696A is packaged in advanced, fully “green” compliant, 2.70 x 2.70mm, 25-bump Wafer-Level ChipScale Package (WLCSP).
