The input signal is referenced to Vcc. When the input voltage Vcc - Vin is higher than the specified Vih threshold, the output power MOSFET is turned-on. When Vcc - Vin is lower than the specified Vil threshold, the output MOSFET is turned-off. A sense current proportional to the current in the power Mosfet is sourced to the Ifb pin. Over-current shutdown occurs when Vfb - Vin > 4.5 V. The current shutdown threshold 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 IR 3310(S) very rugged and suitable for the automotive environment. 5 Lead TO220 IR3310 5 Lead D2Pak (SMD220) IR3310S Typical Connection VCC IN Ifb 10 k IR 3310 OUT LOAD Battery RIfb on off System Ground Power Ground www.irf.com 1 IR3310(S) Absolute Maximum Ratings Absolute maximum ratings indicate sustained limits beyond which damage to the device may ...
