| Content | 1. 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 6V 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. 2. Features and benefits Amplifier Stop/start-car prepared: keeps operating without audible disturbance during engine start at a battery voltage as low as 6 V I2C-bus mode (3.3 V and 5 V compliant) Can drive 2: or 4: loads Speaker fault detection Start-up diagnostics with load detection: open, short, present; filtered for door-slam and chatter relays ACload (tweeter) detection with low and high current mode Gain select after start-up without audible disturbance Programmable gain (26 dB and 16 dB), independently programmable for the front and rear channels Line driver mode (16 dB and mid-tap voltage 0.25VP for stop/start-cars) Programmable clip detection: 2%, 5% or 10% TDF8554J I2C-bus controlled 4 u 45 W power amplifier and multiple voltage regulator Rev. 1 — 31 August 2011Product data sheet |
