IPS1051LPbF / IPS1052GPbF
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 IPS1051LPbF and IPS1052GPbF are Intelligent
Power Switches (IPS) featuring low side MOSFETs with
over-current, over-temperature, ESD protection and drain
to source active clamp. The IPS1052G is a dual channel
device while the IPS1051 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 3A. 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.
