Features

IPS5451/IPS5451S

Data Sheet No.PD60159-J

Description

The IPS5451/IPS5451S are fully protected five terminal

high side switch with built in short circuit, over-tempera-

ture, ESD protection, inductive load capability and

diagnostic feedback. The over-current protection latches

off the device if the output current exceeds Ishutdown.

It can be reset by turning the input pin low. The over-

temperature protection turns off the high side switches

if the junction temperature exceeds Tshutdown. It will

below Tshutdown. A diagnostic pin is provided for status

feedback of over-current, over-temperature and open

load detection. The double level shifter circuitry allows

large offsets between the logic ground and the load

ground.
