DETAILED DESCRIPTION

The SiP32101, SiP32102, and SiP32103 bidirectional

switches feature reverse blocking capability to isolate the

battery from the system. The internal switch has an ultra-low

6.5 m

Ω (typ. at 3.3 V) on-resistance and operates from a

+2.3 V to +5.5 V input voltage range, making the device ideal

battery-disconnect

switch

for

high-capacity

battery

applications. The parts can handle 7 A continuous current at

both directions.

The SiP32101, SiP32102, and SiP32103 have slew rate

control, making them ideal in large load capacitor as well as

high-current load switching applications.

The SiP32101, SiP32102, and SiP32103 are available in an

ultra compact 12-Bump, 1.3 mm x 1.7 mm, 0.4 mm pitch

WCSP package with top side lamination. The device

operates over the temperature of -40 °C to +85 °C.

REVERSE CURRENT BLOCKING

The SiP32101, SiP32102, and SiP32103 are bidirectional

switches that prevent current flowing from either port to the

other when the device is disabled.

EN, EN INPUT

SiP32101 and SiP32103 have an active-low enable pin

which can interface with low voltage GPIO directly. The

switch is on when EN is low and off when EN is high. The

SiP32102 has an active-high enable pin that turns the switch

on when high and off when low. The SiP32101 and

SiP32102 have an integrated pull down resistor at EN pin.

The SiP32103 EN pin integrates a pull up resistor that will

automatically connected to either port A or port whichever

is of higher voltage.

SWITCH ON AND OFF PERFORMANCE

The SiP32101, SiP32102, and SiP32103 have slew rate

control. This minimizes the inrush current and provides a

soft turn on.
