IRS21091SPBF

Gate Driver Overview

The IRS21091SPBF is a high-voltage, high-speed power MOSFET and IGBT driver featuring dependent high-side and low-side referenced output channels. It operates with a gate drive supply range of 10V to 20V and supports logic inputs compatible with 3.3V, 5V, and 15V levels. The device includes undervoltage lockout for both channels to ensure reliable operation. Designed for robust performance, it utilizes proprietary HVIC technology to prevent latch-up conditions during high dv/dt events.
