The IR21814SPBF is a high voltage, high speed gate driver IC designed for driving power MOSFETs and IGBTs in half-bridge configurations. It features independent high and low side output channels and is capable of operating with a floating channel up to 600V. The device supports a gate drive supply range from 10V to 20V and is compatible with 3.3V and 5V logic levels. Key specifications include an output source current capability of 1.4A and sink current capability of 1.8A, along with matched propagation delays for both channels, enhancing performance in switching applications. The IR21814SPBF also incorporates undervoltage lockout protection for both channels, ensuring reliable operation. Its ruggedized monolithic construction is achieved through proprietary HVIC and latch immune CMOS technologies, making it suitable for industrial applications. The device is available in lead-free packaging options.
