SIP32101 EVALUATION BOARD
SiP32101 demo board is designed to evaluate the low
RDS(on) and bidirectional function of the device.
Power Input and Output Terminals:
These power header terminals (J1 and J2) are designed for
easily hood up to the power supply and the load for the
evaluation (see fig. 1). The input voltage range for this
evaluation is from 2.3 V to 5.5 V. The header J1 is Power Port
B. The header J2 is Power Port A. To measure the device
resistance, please probe the voltage at K-B (J4) and K-A (J3)
illustrated at “Power Port Voltage Sense” section.

DESCRIPTION
The SiP32101 bidirectional battery switch features 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 SiP32101
has slew rate control, making it ideal in large load capacitor
as well as high-current load switching applications. The
device also has ultra low operation current. Its shutdown
current is of 10 pA (typ.) and quiescent current of 15 pA. The
SiP32101 is logic low enable. It can interface with low
voltage control signal directly. The SiP32101 is available
in an ultra compact 12 bump WCSP package with top
size lamination. The device operates over the temperature of
-40 °C to +85 °C.
