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 mΩ (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.
