DescriptionThe TAS5352A device is a high-performance,
integrated stereo digital amplifier power stage
designedto drivea 4-Ω bridge-tied load (BTL)at up 125 W per channel with low harmonic distortion,
low integrated noise, and low idle current.
The TAS5352A hasa complete protection system
integrated on-chip, safeguarding the device againsta
wide rangeof fault conditions that could damage the
system. These protection features are short-circuit
protection, overcurrent protection, undervoltage
protection, overtemperature protection, anda lossof
PWM signal (PWM activity detector). power-on-reset (POR) circuitis usedto eliminate
power-supply sequencing thatis required for most
power-stage designs.
