Infineon Technologies' IR21844S is a high-performance, half-bridge gate driver IC designed for driving IGBT and N-channel MOSFET power switches. Featuring a non-inverting input logic, this device offers two independent channels with a peak output current of 1.9A source and 2.3A sink. The driver operates with a supply voltage range of 10V to 20V and supports bootstrap configurations up to 600V for the high-side driver. Typical rise and fall times are 40ns and 20ns respectively. The logic thresholds are set at 0.8V for VIL and 2.7V for VIH. Packaged in a 14-SOIC (0.154" width) surface-mount configuration, the IR21844S is suitable for demanding applications across industrial power supplies, motor control, and automotive electronics, operating within an ambient temperature range of -40°C to 150°C.
