DESCRIPTION

SiP43102 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

pins are non-inverting inputs which control the output of

switch 1 and switch 2 respectively. SiP43102 contains under

voltage lockout, UVLO, a user definable turn on delay, current

limit, short circuit protection, and thermal shutdown.

The SiP43102 is available in 16-pin TSSOP and PowerPAKr

MLP-44 packages, which are specified over the industrial,

D suffix (−40 to 85_C) temperature range. Both standard and

lead (Pb)-free options are available in the 16-pin TSSOP

package.
