AUIPS7121R

August, 27th 2009 Automotive grade AUIPS7121R CURRENT SENSE HIGH SIDE SWITCH Features Suitable for 24V systems Over current shutdown Over temperature shutdown Current sensing Active clamp Optimized Turn On/Off for EMI Reverse battery protection (Mosfet on) 75W Filament lamp Solenoid 24V loads for trucks Product Summary Rds(on) 30mΩ max. Vclamp 65V Current shutdown 50A min. Applications Packages Description The AUIPS7121R is a fully protected five 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 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. www.DataSheet4U.com Typical Connection DPak Vcc IN Ifb Current feeback Input On Off AUIPS7121R Battery Out 10k Rifb Logic Ground Power Ground Load www.irf.com Subject to change without notice 1 AUIPS7121R Qualification Information† Qualification Level Automotive (per AEC-Q100††) Comments: This family of ICs has passed an Automotive qualification.
