Infineon Technologies IR21844 is a high-performance, dual-channel, half-bridge gate driver IC in a 14-DIP package. This non-inverting driver facilitates efficient control of IGBT and N-Channel MOSFET power switches. It features independent high-side and low-side outputs, each capable of sourcing 1.9A and sinking 2.3A peak current, with typical rise and fall times of 40ns and 20ns respectively. The device supports a high-side voltage of up to 600V and operates from a supply voltage range of 10V to 20V. Designed for robust operation, the IR21844 maintains functionality across an extended temperature range of -40°C to 150°C. Applications include motor control, power factor correction (PFC), and switch mode power supplies (SMPS).
