The IR2125 is a high voltage, high speed power MOSFET and IGBT driver with over-current limiting protection circuitry. It features a floating channel designed for bootstrap operation and is fully operational up to +500V. It is also tolerant to negative transient voltage and dV/dt immune. The driver has a gate drive supply range from 12 to 18V, undervoltage lockout, and a current detection and limiting loop to limit the driven power transistor current. An error lead indicates fault conditions and programs shutdown time. The output is in phase with the input.
The IR2125 is a high voltage, high speed power MOSFET and IGBT driver featuring proprietary HVIC and latch immune CMOS technologies. It includes over-current limiting protection circuitry that detects current in the driven power transistor and limits the gate drive voltage to prevent damage. The device is designed for bootstrap operation with a floating channel capable of driving N-channel power MOSFETs or IGBTs in high or low side configurations up to 500 volts.
