IPS1041(L)(R)PbF / IPS1042GPbF
SINGLE/DUAL CHANNEL
INTELLIGENT POWER LOW SIDE SWITCH
Features
• 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
Description
The IPS1041(L)(R)PbF and IPS1042GPbF 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
IPS1042G is a dual channel device while the IPS1041 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.
