International Rectifier IR25750L Current Sensing IC

International Rectifier IR25750L current sensing IC extracts the VDS(on) of a power MOSFET, or the VCE(on) of an IGBT, during the switch on-time. IR's proprietary 600V HVIC technology then 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 and synchronizes the internal sensing circuit to the on and off times of the switch. Programmability and temperature compensation are also possible.
