AUIR3320S 1 www.irf.com ? 201 2 international rectifier august , 13 th 2012 automotive grade low emi current sense high side switch features load current feedback programmable over current shutdown active clamp esd protection input referenced to vcc over temperature shutdown switching time optimized for low emi reverse battery protection lead - f ree, halogen - free, rohs compliant description the au ir 3320 (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 tur ned on. when the vcc - vin is lower than the specified 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 th reshold is adjusted by selecting the proper rifb. 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 ru gged in automotive environment. product summary rds(on) 4 m max. vcc op. 6 to 26v current ratio 6 0 00 prog. ishutdown 10 to 55 a vclamp 40v packages d2pak pin 4 and 5 fused au ir 3320 s o rdering information base part number package type standard pack complete part number form quantity AUIR3320S d2 - pak - 5 - leads tube 50 AUIR3320S tape and reel left 800 AUIR3320Strl tape and reel right 800 AUIR3320Strr www.datasheet.net/ datasheet pdf - http://www..co.kr/
