Interlink Electronics, Inc. Gate Drivers IR2109STRPBF

The IR2109STRPBF is a high voltage, high speed gate driver IC designed for driving power MOSFETs and IGBTs in half-bridge configurations. It operates with a floating channel capable of handling voltages up to 600V, making it suitable for various industrial applications. The device features a gate drive supply range of 10 to 20V and is compatible with 3.3V, 5V, and 15V logic inputs. Key specifications include an internal dead-time of 540ns, which can be programmed up to 5µs with an external resistor, and a matched propagation delay for both high and low side outputs. The IR2109 also incorporates undervoltage lockout for both channels and cross-conduction prevention logic to enhance reliability. It is available in multiple package options, including 8-lead and 14-lead configurations in both SOIC and PDIP formats. Engineers considering this product should note its robust design, which includes latch immune CMOS technology, and its ability to provide lower di/dt for improved noise immunity.
