IPS521/IPS521S
FULLY PROTECTED HIGH SIDE POWER MOSFET SWITCH
Features
Over temperature protection (with auto-restart)
Short-circuit protection (current limit)
Active clamp
E.S.D protection
Status feedback
Open load detection
Logic ground isolated from power ground
Description
The IPS521/IPS521S are fully protected five terminal
high side switches with built in short-circuit , over-
temperature, ESD protection, inductive load capability
and diagnostic feedback. The output current is con-
trolled when it reaches Ilim value. The current
limitation is activated until the thermal protection
acts. The over-temperature protection turns off the
high side switch if the junction temperature exceeds
Tshutdown. It will automatically restart after the junc-
tion has cooled 7oC below Tshutdown. A diagnostic
pin is provided for status feedback of short-circuit,
over-temperature and open load detection. The double
level shifter circuitry allows large offsets between the
logic ground and the load ground.
