500 V bootstrap, 2 A peak — the half-bridge driver for motor and power applications
The Infineon IR2110-1 is a high-voltage half-bridge gate driver rated for a 500 V bootstrap supply on the high side, with 2 A peak source and sink current capability for driving IGBTs and N-channel MOSFETs in a half-bridge or full-bridge topology. The independent non-inverting input channels let the designer control the high-side and low-side switches separately, which is the standard interface for PWM-driven motor drives, DC-DC converters, and UPS inverters.
Switching speed and gate drive headroom
The 3.3 V to 20 V supply range covers both logic-level and standard gate-drive rails. Logic input thresholds of 6 V (VIL) and 9.5 V (VIH) are set for 15 V logic families common in industrial control — a 3.3 V MCU output will not reliably drive the input without a level shifter.
