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).
