AUIR3317

August, 25th 2011 Automotive grade AUIR3317(S) LOW EMI CURRENT SENSE HIGH SIDE SWITCH Features x x x x x x x x Product Summary Rds(on) 7 m: max. Vcc op. 6 to 26V Current Ratio 8800 Over-current 120A Vclamp 40V Load current feedback Over current shutdown Active clamp ESD protection Input referenced to Vcc Over temperature shutdown Switching time optimized for low EMI Reverse battery protection Package Description The AUIR3317(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 specified Vil threshold, the output Mosfet is turned off. A current proportional to the power Mosfet current is sourced to the Ifb pin. 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.
