Brief Description

The KTS1656 features two low resistance power switches

configured as single input, dual output, change-over

switch. The input to both switches is protected against

VBUS surge voltages of up to ±200V, and is also protected

against over-voltage, with preset trip points on both the

VBUS-to-VOUT and VBUS-to-SYS paths, providing

protection to downstream components from abnormal input

conditions.

The main switch (VBUS-to-VOUT) is an active-LOW

enabled, reverse-blocking 3.5A rated MOSFET, with an

OVP trip point of 13.9V. The secondary switch (VBUS-to-

SYS) is an active-HIGH enabled, reverse-blocking, 6.0A

rated MOSFET, with an OVP trip point of 5.25V. The VBUS

input is rated from -6V to 28V.

When VBUS is greater than 2.5V typ, the LDO output

provides an “always ON” power source, regardless of the

OVLO, ̅E̅̅N̅̅1̅ and EN2 state, to power downstream

components, thereby permitting operation without an

installed battery.

The KTS1656 also features an active-HIGH SHDN pin to

conserve power and an over-temperature thermal

protection.

The KTS1656 is packaged in advanced, fully “green”

compliant, 2.71 x 3.01mm, Wafer-Level Chip-Scale

Package (WLCSP).
