IR21531S - SELF-OSCILLATING HALF-BRIDGE DRIVER

Download the IR21531S datasheet PDF. This datasheet also covers the IR21531 variant, as both devices belong to the same self-oscillating half-bridge driver family and are provided as variant models within a single manufacturer datasheet.

Description

8 Lead PDIP 8 Lead SOIC The IR21531(D)(S) are an improved version of the popular IR2155 and IR2151 gate driver ICs, and incorporates a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer.

Features

  • Integrated 600V half-bridge gate driver 15.6V zener clamp on Vcc True micropower start up Tighter initial deadtime control Low temperature coefficient deadtime Shutdown feature (1/6th Vcc) on CT pin Increased undervoltage lockout Hysteresis (1V) Lower power level-shifting circuit Constant LO, HO pulse widths at startup Lower di/dt gate driver for b.
