Description

KTS1672 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. 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.

KTS1672 has automatic reverse-current blocking feature which 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. An ACOK or ACOK flag indicates when power is good.

KTS1672 is packaged in advanced, fully “green” compliant, 2.18 x 1.64mm, 12-bump Wafer-Level Chip Scale Package (WLCSP).
