TDF8544

C-bus controlled 4



50 W power amplifier

Rev. 2 — 29 August 2011

Product data sheet

1. General description

The TDF8544 is one of a new generation of complementary quad Bridge-Tied Load (BTL)

audio power amplifiers intended for automotive applications. It has full I

C-bus controlled

diagnostics, including start-up diagnostics. The TDF8544 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.

2. Features and benefits



Stop/start-car prepared: keeps operating without audible disturbance during engine

start at a battery voltage as low as 6 V



Operates in either legacy (non I

C-bus) or I

C-bus modes (3.3 V and 5 V compliant)



Four hardware-programmable I

C-bus addresses



Can drive 2



and 4



loads



Speaker fault detection



Start-up diagnostics with load detection: open, short, present; filtered for door-slam

and chatter relays



AC load (tweeter) detection with low and high current mode



Gain select after start-up without audible disturbance



Independent selectable soft mute of front and rear channels



Programmable gain (26 dB and 16 dB), independently programmable for the front and

rear channels



Line driver mode supports engine start at a battery voltage as low as 6 V (16 dB and

mid-tap voltage 0.25V

)



Programmable clip detect: 2 %, 5 % or 10 %



Programmable thermal pre-warning



Pin STB can be programmed/multiplexed with second-clip detect



Clip information of each channel can be directed separately to pin DIAG or pin STB



Independent enabling of thermal-, clip- or load fault information (short across the load

or to V

or to ground) on pin DIAG



Loss-of-ground and open V

safe (minimum series resistance required)



All amplifier outputs short-circuit proof to ground, supply voltage and across the load

(channel independent)



All pins short-circuit proof to ground
