Half-bridge driver for 600 V bus rails
The IR2101STR is a half-bridge gate driver from Infineon (formerly International Rectifier) designed to drive IGBTs and N-channel MOSFETs in high-side/low-side configurations. Its bootstrap topology handles a high-side voltage up to 600 V, making it a fit for motor drives, UPS inverters, and DC-DC converters where the bus rail sits below that ceiling.
Output current and switching speed
That sink current drives the gate charge off quickly, which matters for reducing switching losses in hard-switched topologies. The 10 V to 20 V supply range covers standard gate drive levels for both IGBTs and MOSFETs.
