Vclamp 70V Ishutdown 1.8A (typ.) Applications   Packages Solenoids and relays 24V truck loads Description The AUIPS2051L/AUIPS2052G 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. The AUIPS2052 is a dual channel device while the AUIPS2051 is a single channel.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 1.8A. 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.
