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

IR2153 600V Self-Oscillating Half-Bridge Gate Driver IC with Micropower Startup

The IR2153 is an advanced self-oscillating half-bridge gate driver IC engineered for demanding high-voltage applications. It seamlessly integrates a robust 600V half-bridge gate driver with a front-end oscillator, significantly simplifying circuit design. This IC represents a superior evolution of the popular IR2155 and IR2151 gate drivers. Key enhancements include true micropower start-up, ensuring highly efficient power management from the outset. It also offers tighter initial deadtime control, which is crucial for optimizing switching performance and minimizing losses. An increased undervoltage lockout hysteresis guarantees more stable and reliable operation across varying conditions. The IR2153 stands as an excellent choice for a wide array of high-voltage power management systems. It provides a highly reliable and efficient solution for precisely driving power MOSFETs and IGBTs.
