Infineon Technologies AUIRS21844S is a high-voltage, high-speed, two-channel, half-bridge gate driver IC. This device is designed for driving N-channel MOSFETs and IGBTs in automotive applications, meeting AEC-Q100 qualification. It features a non-inverting input and supports a high-side voltage of up to 600V with bootstrap operation. The AUIRS21844S provides robust gate drive with peak output currents of 1.9A sourcing and 2.3A sinking. Its typical rise and fall times are 15ns and 12ns respectively, enabling efficient switching. The logic voltage thresholds are 0.8V for VIL and 2.5V for VIH. Operating from a 10V to 20V supply, this component is housed in a 14-SOIC surface-mount package and operates across a junction temperature range of -40°C to 150°C. It is commonly utilized in automotive power management systems and electric vehicle powertrains.
