Diagnostic on the input current
Description
The AUIPS1041(L)(R) and AUIPS1042G are three
terminal Intelligent Power Switches (IPS) featuring low
side MOSFETs with over-current, over-temperature, ESD
protection and drain to source active clamp. The
AUIPS1042G is a dual channel device while the
AUIPS1041 is a single channel. These devices offer
protections and the high reliability required in harsh
environments. Each switch provides efficient protection by
turning OFF the power MOSFET when the temperature
exceeds 165°C or when the drain current reaches 4.5A.
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.
