IC revision2

Description

The IRS20957S 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 conditions during positive and negative load currents without any external shunt resistors. A built-in protection control block provides a secure protection sequence against over-current conditions and a programmable reset timer.The internal dead-time generation block enables accurate gate switching and optimum dead-time setting for better audio performance, such as lower THD and lower audio noise floor.

Features

  • Floating PWM input enables easy half bridgeimplementation
  • Programmable bidirectional over-current protection withself-reset function
  • Programmable preset dead-time for improved THDperformances
  • High noise immunity
  • +/-100V ratings deliver up to 500W in output power
  • 3.3 V/ 5 V logic compatible input
  • Operates up to 800kHz

Typical applications

  • Home theatre systems / Mini component stereo systems / Powered speaker systems / General purpose audio power amplifiers
