Data Sheet No. PD60288 D IR3313(S)PbF PROGRAMMABLE CURRENT SENSE HIGH SIDE SWITCH Features Product Summary Load current feedback Rds(on) 7 m max. Programmable over current shutdown Vcc op. 6 to 32V Active clamp Current Ratio 8800 ESD protection Input referenced to Vcc Prog. Ishutdown 10 to 90A Over temperature shutdown Vclamp 40V Reverse battery protection Description Packages The IR3313(S)PbF 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 TO-220 DPak current shutdown occurs when Vst-Vin > 4.5V. The current IR3313 Pin 4 and 5 fused shutdown threshold is adjusted by selecting the proper IR3313S 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 rugged in automotive environment.
