General description
The TDF8554J is one of a new generation of complementary quad Bridge-Tied Load
(BTL) audio power amplifiers with full I2C-bus controlled diagnostics, multiple voltage
regulator and two power switches intended for automotive applications.
The TDF8554J can operate at a battery voltage as low as 6 V making this amplifier
suitable for stop/start-car operation. The amplifier uses a complementary DMOS output
stage in a Silicon-On-Insulator (SOI)-based BCD process. The DMOS output stage
ensures a high power output signal with perfect sound quality. The SOI-based BCD
process ensures a robust amplifier, where latch-up cannot occur, with good separation
between the four independent channels with every component isolated and without
substrate currents.
The multiple voltage regulator comprises four programmable voltage regulators, one
standby regulator and two power switches.
The TDF8554J is soft- and hardware downwards-compatible with its predecessor
TDA8589XJ.
The TDF8554J includes features, such as selectable undervoltage for stop/start-cars
which can be selected with additional I2C-bus instruction bytes. If these additional bytes
are not sent, the TDF8554J has the same functionality as its predecessor IPAS
TDA8589XJ.
