International Rectifier IRS20965 Digital
Class D Audio Driver IC
International Rectifier's IRS20965 Digital Class D Audio Driver IC with protected Pulse Width Modulation (PWM) switching and a full complement of audio MOSFETs is optimized for high performance Class D audio amplifier applications. The IRS20965 features high-side and low-side independent floating PWM input to allow deadtime control from an external PWM controller. Shoot-through prevention logic provides additional safety in the event of PWM controller failure. The new IC also features over-current sensing output and 2A gate drive output capability. Operating up to 800kHz, other key features of the IRS20965 include programmable bidirectional over-current detection with self-reset function, high noise immunity, ±100V ratings to deliver up to 500W in output power and 3.3V / 5V logic compatible input.
