IR25603SPBF - Self-Oscillating Half-Bridge Driver

This page provides the datasheet information for the IR25603SPBF, a member of the IR25603PBF Self-Oscillating Half-Bridge Driver family.

Description

The IR25603(S) incorporates a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer.

A shutdown feature has been designed into the CT pin, so that both gate driver outputs can be disabled using a low voltage control signal.

Features

  • Self-Oscillating Half-Bridge Driver Product Summary.
  • Floating channel designed for bootstrap operation.
  • Integrated 600 V half-bridge gate driver.
  • 15.6 V zener clamp on Vcc.
  • True micropower start up.
  • Tighter initial dead time control.
  • Low temperature coefficient dead time.
  • Shutdown feature (1/6th Vcc) on CT pin.
  • Increased undervoltage lockout Hysteresis (1 V).
  • Lower power level-shifting circuit.
  • Constant LO, HO pulse widths at startup.
  • Lowe.
