SOT-23 Current Sensing IC
Features
Description
 VDS(on) or VCE(on) sensing
 Eliminates external current sensing resistors
The IR25750L is a novel current sensing IC that
 Enables inductance-less current sensing
extracts the VDS(on) of a power MOSFET, or the
 ^{600V blocking capability}
VCE(on) of an IGBT, during the switch on-time.
 Programmability and temperature compensation possible ^{IR’s proprietary 600V HVIC technology then}
 ^{No VCC required}
 ^{Gate drive on/off sync input}
 ^{Filter delay at GATE turn-on (200nsec typ.)}
 ^{20.8V zener clamps on GATE and CS pins}
 Integrated ESD protection and latch immunity on all pins
blocks the high drain voltage to during the
MOSFET or IGBT off-time. This IC allows for
external current sensing resistors to be eliminated
for reducing power losses and increasing overall
system efficiency. The IC includes a gate drive
input that provides VCC supply voltage to the IC
