The IR211/IR221 half-bridge gate driver IC is a high-performance half-bridge gate driver with floating channel, soft over-current shutdown, synchronization signal, integrated desaturation detection circuit, two-stage turn-on output for di/dt control, separate pull-up/pull-down output drive pins, matched delay outputs, undervoltage lockout with hysteresis band, suitable for driving a single half bridge in power switching applications.
The IR2114/IR21141 and IR2214/IR22141 SSPbF families are half‑bridge gate driver ICs designed for power‑switching applications. They provide high gate‑driving capability (2 A source, 3 A sink) and feature soft over‑current shutdown, desaturation detection, and undervoltage lockout.
Key specifications include floating channel voltages up to +1200 V, dead‑time matching of 75 ns (max) and 330 ns (typ), and a 24‑lead SSOP package. The devices support bootstrap operation, fault communication via SY_FLT and FAULT/SD pins, and are lead‑free compliant.
