Brief Description

The KTS1697A is a low-resistance, high-current load

switch with soft-start, over-voltage protection, “ideal

diode” reverse-current protection with fast recovery,

short-circuit protection, over-current protection, overtemperature

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” with fast recovery 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 KTS1697A is packaged in advanced, fully “green”

compliant, 2.70 x 2.70mm, 25-bump Wafer-Level Chip-

Scale Package (WLCSP).

Applications

• Notebooks, Netbooks, Ultra-Books, Tablets

• Mini Desktop PCs, Docking Stations, Monitors
