The Infineon IR21531 is a self-oscillating half-bridge gate driver IC designed for efficient power management applications. It integrates a high-voltage half-bridge gate driver with a front-end oscillator, similar to the industry-standard CMOS 555 timer.
Key electrical features include an integrated 600V half-bridge gate driver, a 15.6V zener clamp on Vcc, and true micropower startup. The device offers tighter initial deadtime control with a low temperature coefficient and a shutdown feature on the CT pin. Noise immunity is improved through lower peak di/dt and increased undervoltage lockout hysteresis.
This gate driver IC is available in 8-lead PDIP and 8-lead SOIC packages. It provides excellent latch immunity on all inputs and outputs and features ESD protection on all leads. The IR21531 is suitable for various power conversion designs requiring a robust and easy-to-use half-bridge driver solution.
