TDF8541TH/N2規(guī)格書詳情

General description

The TDF8541 is one of a new generation of complementary quad Bridge-Tied Load (BTL)

audio power amplifiers intended for automotive applications. It has full I2C-bus controlled

diagnostics, including start-up diagnostics. The TDF8541 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.

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 I2C-bus) or I2C-bus modes (3.3 V and 5 V compliant)

Four hardware-programmable I2C-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 0.25VP)

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 VP or to ground) on pin DIAG

Loss-of-ground and open VP 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
