DESCRIPTION

The TAS5152 is a third-generation, high-performance,
integrated stereo digital amplifier power stage with
improved protection system. The TAS5152 is capable
of driving a 4-Ω bridge-tied load (BTL) at up to 125 W
per channel with low integrated noise at the output, low
THD+N performance, and low idle power dissipation.
A low-cost, high-fidelity audio system can be built using
a TI chipset, comprised of a modulator (e.g., TAS5508)
and the TAS5152. This system only requires a simple
passive LC demodulation filter to deliver high-quality,
high-efficiency audio amplification with proven EMI
compliance. This device requires two power supplies,
12 V for GVDD and VDD, and 35 V for PVDD. The
TAS5152 does not require power-up sequencing due to
internal power-on reset. The efficiency of this digital
amplifier is greater than 90% into 6 Ω, which enables the
use of smaller power supplies and heatsinks.
The TAS5152 has an innovative protection system
integrated on-chip, safeguarding the device against a
wide range of fault conditions that could damage the
system. These safeguards are short-circuit protection,
overcurrent protection, undervoltage protection, and
overtemperature protection. The TAS5152 has a new
proprietary current-limiting circuit that reduces the
possibility of device shutdown during high-level music
transients. A new programmable overcurrent detector
allows the use of lower-cost inductors in the
demodulation output filter.
