TDF8541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
