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.
