DESCRIPTION
SiP43101 is a dual power switch IC which contains all control
and power switching circuitry required to drive resistive and
inductive loads in industrial applications. The output switches
are NPN power transistors which can be configured as either
high-side or low-side switches. These switches can operate
from voltages as high as 35 V and have a continuous output
current rating of 200 mA, combined or individually. Internal
zener diodes are provided to clamp the power switch voltages
to safe levels when driving inductive loads. The IN1 pin is a
non-inverting input which controls the output of switch 1.
A 2-input Exclusive OR gate input controls switch 2, allowing
switch 2 to be controlled by either an inverting or non-inverting
control signal. SiP43101 contains under voltage lockout,
UVLO, a user definable turn on delay, current limit, short
circuit protection, and thermal shutdown.
The SiP43101 is available in both standard and lead (Pb)-free
16-pin TSSOP and PowerPAKr MLP-44 packages, which are
specified over the industrial, D suffix (–40 to 85_C) tem–
perature range.
