INFINEON IR2125PBF Power Driver Module

The IR2125PBF is a high-voltage, high-speed power MOSFET and IGBT driver with integrated over-current protection circuitry. Utilizing proprietary HVIC and latch-immune CMOS technology, it features a rugged monolithic design. The device's logic inputs are compatible with standard CMOS or LSTTL levels, down to 2.5V. Its output driver includes a high pulse current buffer for minimal cross-conduction. The protection circuitry detects over-current conditions in the driven transistor and limits the gate drive voltage accordingly. Cycle-by-cycle shutdown can be controlled externally via a capacitor, which determines the duration between over-current detection and latch shutdown. The floating channel allows for high or low-side drive of N-channel power MOSFETs or IGBTs operating up to 500V. The device is immune to negative transient voltages (DV/DT), features under-voltage lockout, current limiting, and fault indication. It provides an output phase-aligned with the input. Suitable for industrial and consumer electronic applications.
