Automotive grade AUIR3320S LOW EMI CURRENT SENSE HIGH SIDE SWITCH Features Product Summary Load current feedback Rds(on) 4 m max. Programmable over current shutdown Vcc op. 6 to 26V Active clamp Current Ratio 6000 ESD protection Input referenced to Vcc Prog. Ishutdown 10 to 55A Over temperature shutdown Vclamp 40V Switching time optimized for low EMI Reverse battery protection Lead-Free, Halogen-Free, RoHS compliant Packages Description The AUIR3320(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. Over current shutdown occurs when Vifb-Vin > 4.7V. The DPak current shutdown threshold is adjusted by selecting the Pin 4 and 5 fused proper RIfb. Either over current and over temperature AUIR3320S 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.
