Features

  • TAS6584-Q1 is the first 45-V automotive Class-D audio amplifier with integrated current sense and integrated Class-H control in the industry. The device delivers maximum output power and high-fidelity audio
  • LM5123-Q1 is a 2.2-MHz wide-VIN low-IQ synchronous boost controller with a TRACK pin for simplified tracking power-supply design
  • Self-contained Class-H control allows for simplified implementation in external amplifier applications and minimizes the need for additional digital power controller or software
  • Includes an input protection circuit to protect against external transients, reverse battery conditions, and system overcurrent events
