The TAS5342 is a high-performance, integrated stereo digital amplifier power stage designed to drive a 4- bridge-tied load (BTL) at up to 100 W per channel with low harmonic distortion, low integrated noise, and low idle current.
The TAS5342 has a complete protection system integrated on-chip, safeguarding the device against a wide range of fault conditions that could damage the system. These protection features are short-circuit protection, over-current protection, under voltage protection, over temperature protection, and a loss of PWM signal (PWM activity detector).
A power-on-reset (POR) circuit is used to eliminate power-supply sequencing that is required for most power-stage designs.
