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).
