IPS6044GPBF

Data sheet No. PD60350 IPS6044GPbF INTELLIGENT POWER HIGH SIDE SWITCH Features • • • • • • • • • Over temperature shutdown (with auto-restart) Short circuit protection (current limit) Reverse battery protection (turns On the MOSFET) Full diagnostic capability (short circuit to battery) Active clamp Open load detection in On and Off state Ground loss protection Logic ground isolated from power ground ESD protection Product Summary Rds(on) Vclamp I Limit Open load Package 130mΩ max. 39V 7A 3V / 0.22A Description The IPS6044GPbF is quad output Intelligent Power Switch (IPS) for use in a high side configuration. It features short circuit, over-temperature, ESD protection, inductive load capability and diagnostic feedback. The output current is limited to the Ilim value. The current limitation is activated until the thermal protection acts. The over-temperature protection turns off the device if the junction temperature exceeds the Tshutdown value. It will automatically restart after the junction has cooled 7°C below the Tshutdown value. The reverse battery protection turns On the MOSFET. A diagnostic pin provides different voltage levels for each fault condition. The double level shifter circuitry will allow large offsets between the logic and load ground.
