IPS5451/IPS5451S
FULLY PROTECTED HIGH SIDE POWER MOSFET SWITCH
Features
Over temperature protection (with auto-restart)
Over current shutdown
Active clamp
E.S.D protection
Status feedback
Open load detection
Logic ground isolated from power ground
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
automatically restart after the junction has cooled 7oC
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.
