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 PowerPAK

r MLP-44 packages, which are

specified over the industrial, D suffix (–40 to 85

_C) tem–

perature range.
