IR25603PBF - Self-Oscillating Half-Bridge Driver

General 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.
