August, 27th 2009 Automotive grade AUIPS7141R CURRENT SENSE HIGH SIDE SWITCH Features Product Summary Suitable for 24V systems Over current shutdown Rds(on) 100m max. Over temperature shutdown Vclamp 65V Current sensing Active clamp Current shutdown 20A min. Low current ESD protection Optimized Turn On/Off for EMI Applications 21W Filament lamp Packages Solenoid 24V loads for trucks Description The AUIPS7141R is a fully protected four terminal high side switch specifically designed for driving lamp. It features current sensing, over-current, over-temperature, ESD protection and drain to source active clamp. When the input voltage Vcc - Vin is higher than the specified DPak threshold, the output power Mosfet is turned on. When the Vcc - Vin is lower than the specified Vil threshold, the output Mosfet is turned off. The Ifb pin is used for current sensing. The over-current shutdown is higher than inrush current of the lamp.
