d ecember , 1 0 th 20 10 automotive grade au ir3313(s) www.irf.com 1 programmable current sense high side switch features load current feedback programmable over current shutdown active clamp esd protection input referenced to vcc over temperature shutdown reverse battery protection lead free, rohs compliant description the au ir3313(s) is a fully protected 4 terminals high side switch. the input signal is referenced to vcc. 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 sp ecified vil threshold, the output mosfet is turned off. a current proportional to the power mosfet current is sourced to the ifb pin. over current shutdown occurs when v ifb - vin > 4. 7 v. the current shutdown threshold is adjusted by selecting the proper rif b. either over current and over temperature latches off the switch. the device is reset by pulling the input pin high. other integrated protections (esd, reverse battery, active clamp) make the switch very rugged in automotive environment. product summar y rds(on) 7 m max. vcc op. 6 to 32v current ratio 8800 prog. ishutdown 10 to 90a vclamp 40v packages to - 220 d2pak au ir3313 pin 4 and 5 fused au ir3313s typical connection out AUIR3313 in rifb vcc load battery input power ground ifb logic ground current feeback 10k on off
