IRS20955PBF - PROTECTED DIGITAL AUDIO DRIVER

Description

The IRS20955 is a high voltage, high speed MOSFET driver with a floating PWM input designed for Class D audio amplifier applications.

Bi-directional current sensing detects over-current www.DataSheet4U.com conditions during positive and negative load currents without any external shunt resistors.

Features

  • Floating PWM input enables easy half-bridge implementation Programmable bidirectional over-current protection with self-reset function Programmable preset deadtime for improved THD performances High noise immunity ±100 V ratings deliver up to 500 W in output power 3.3 V/5 V logic compatible input Operates up to 800 kHz RoHS compliant Product Summary.
