IPS1021(S)(R)
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 IPS1021(S)(R) 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. 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 35A. 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.
