Kinetic Technologies KTS1698 VBUS Current-Sink Protection Load Switch

Kinetic Technologies KTS1698 VBUS Current-Sink Protection Load Switch is optimized to protect systems with USB Type-C™ PD ports and barrel connectors. The device is suitable for applications that sink up to 100W at 20V and must withstand up to 29V on VBUS. The KTS1698 features soft-start, over-voltage protection, reverse-current blocking, over-current protection, short-circuit protection, over-temperature protection, and integrated transient-voltage-suppression (TVS).

The KTS1698 includes automatic reverse-current blocking, 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. The integrated TVS provides IEC industry standard ESD and ±90V surge ratings. An ACOK flag indicates when power is good.

The Kinetic Technologies KTS1698 VBUS Current-Sink Protection Load Switch is housed in an advanced, fully “green” compliant Wafer-Level Chip-Scale Package (WLCSP).
