FULLY PROTECTED HIGH SIDE POWER MOSFET SWITCH

International Rectifier 

Data Sheet No.PD 60158-H

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.
