Brief Description

The KTS1688 is a slew-rate controlled, 68mΩ (Typ), low

resistance MOSFET switch intended to be inserted

between a power source and a load to isolate and protect

against abnormal voltage and current conditions. Featuring

slew-rate turn on control, to prevent excessive input

voltage or battery droop resulting from a large inrush

current, the KTS1688 also features several additional

protection functions, such as output over-voltage and input

under-voltage protection, plus over-current (with Fault-flag)

and over-temperature protection.

Operating from a wide input voltage range of 2.5V to 5.5V,

the KTS1688 in the OFF state can block voltages on the

OUT pin of up to 28V. The switch CTRL input is active high

and includes a resistor pull-down.

The device is packaged in advanced, fully “green”

compliant, 1.22mm x 1.22mm, Wafer-Level Chip-Scale

Package (WLCSP).
