IR2102

IR2102 Description

The IR2102 from Infineon Technologies is a high-voltage, high-speed gate driver IC designed for half-bridge configurations in power electronics applications. This obsolete part remains relevant for legacy designs, offering robust performance with a 10V to 20V supply range and 600V bootstrap capability, making it suitable for driving MOSFETs and IGBTs in demanding environments. The IC features two independent channels with inverting inputs, ensuring precise control over switching transitions. Its 100ns rise and 50ns fall times enable efficient high-frequency operation, while the 210mA source and 360mA sink current capabilities ensure strong gate drive for fast switching. Packaged in an 8-pin DIP (Through Hole), the IR2102 is ideal for prototyping and industrial applications where reliability is critical.
