Data Sheet No. PD60297 IPS2041(R)(L)PbF INTELLIGENT POWER LOW SIDE SWITCH Features • • • • • • • Product Summary Over temperature shutdown Over current shutdown Active clamp Low current & logic level input ESD protection Optimized Turn On/Off for EMI Diagnostic on the input current Rds(on) 130mΩ (max.) Vclamp 68V Ishutdown 5A (typ.) Description The IPS2041(R)(L)PbF is a three terminal Intelligent Power Switch (IPS) that features a low side MOSFET with over-current, over-temperature, ESD protection and drain to source active clamp. This device offers protections and the high reliability required in harsh environments. The switch provides efficient protection by turning OFF the power MOSFET when the temperature exceeds 165°C or when the drain current reaches 5A. The device restarts once the input is cycled. A serial resistance connected to the input provides the diagnostic. The avalanche capability is significantly enhanced by the active clamp and covers most inductive load demagnetizations.
