IPS511GTR Datasheet, PDF (1/11 Pages) International Rectifier – FULLY PROTECTED HIGH SIDE POWER MOSFET SWITCH

Data Sheet No.PD60156-K
IPS511G/IPS512G
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 IPS511G/IPS512G are fully protected five terminal
high side switches with built in short-circuit, over-tem-
perature, 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 junction has
cooled 7^oC 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.
