IR2153 - Self-Oscillating Half-Bridge Driver IC (high voltage current) - [Original]

IR2153 Self-Oscillating 600V Half-Bridge Gate Driver IC

The IR2153 is an advanced self-oscillating half-bridge gate driver IC designed for high-voltage applications. It integrates a robust 600V half-bridge gate driver with a front-end oscillator, simplifying circuit design. This IC represents an improved version of the popular IR2155 and IR2151 gate drivers. Key enhancements include true micropower start-up for efficient power management. It also offers tighter initial deadtime control, crucial for optimizing switching performance. An increased undervoltage lockout hysteresis ensures more stable and reliable operation. The IR2153 is an excellent choice for various high-voltage power management systems. It provides a reliable and efficient solution for driving power MOSFETs and IGBTs.
