Brief Description

KTS1698 is a low-resistance, high-current load switch

with soft-start, over-voltage protection, reverse-current

blocking, over-current protection, short-circuit

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 100W

at 20V and must withstand up to 29V on VBUS.

Automatic reverse-current blocking acts as an “ideal

diode” and isolates VBUS when charging or powering

the system via another port. 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. An ̅A̅̅C̅̅O̅̅̅K̅ flag

indicates when power is good.

KTS1698 is packaged in advanced, fully “green”

compliant, 2.62 x 1.64mm, 15-bump Wafer-Level Chip-

Scale Package (WLCSP).
