TAS5342A Datasheet PDF - TI

●The TAS5342A is a high-performance, integrated stereo digital amplifier power stage designed to drive a 4-Ω bridge-tied load (BTL) at up to 100 W per channel with low-harmonic distortion, low-integrated noise, and low-idle current.

●The TAS5342A 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.
