FULLY PROTECTED HIGH SIDE POWER MOSFET SWITCH

International Rectifier 

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 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.
