5A eFuse with Current Limit Control and Reverse Blocking FET Control
Description
KTS1630 is a low-resistance load switch with adjustable current limit, programmable output slew rate during soft-start, over-current protection, short-circuit protection, and over-temperature protection. It is optimized for applications that require adjustable output ramp rate for power sequencing and also need accurate output current limit for safety, such as eFuse protection in consumer appliances. The KTS1630 uses an external resistor to set the current limit and an external capacitor to set the output ramp rate.
To prevent output capacitors being discharged back to input thru the internal body diode when power source at VIN is removed, an additional MOSFET can be connected to the output back-to-back, with its gate connected to BFET pin.
KTS1630 is packaged in advanced, fully “green” compliant, 3mm x 3mm x 0.85mm, 10-pin VDF
