Power Switch Lo Side 0.9A 4-Pin(3+Tab) SOT-223

The AUIPS2051L 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 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.
