Half-bridge driver for 600 V rails
The Infineon IR2103STR is a high-voltage half-bridge gate driver designed to drive both IGBTs and N-Channel MOSFETs in a half-bridge configuration. Its bootstrap topology handles a high-side voltage up to 600 V, making it suitable for motor drives, power inverters, and switched-mode power supplies where the floating high-side gate must be referenced to the switching node.
Gate drive strength and switching speed
The asymmetric sink/source ratio helps pull the gate down quickly during turn-off, reducing cross-conduction in the half-bridge. The 10 V to 20 V supply range covers standard bias rails for industrial gate drive circuits.
No official successor is listed on the record.
