TDF8541J

I2C-bus controlled 4 x 45 W power amplifier; Stop/start-car prepared: keeps operating without audible disturbance during enginestart at a battery voltage as low as 6 V\nOperates in either legacy (non I²C-bus) or I²C-bus modes (3.3 V and 5 V compliant)\nFour hardware-programmable I²C-bus addresses\nCan drive 2 Ω and 4 Ω loads\nSpeaker fault detection\nStart-up diagnostics with load detection: open, short, present; filtered for door-slamand chatter relays\nAC load (tweeter) detection with low and high current mode\nGain select after start-up without audible disturbance\nIndependent selectable soft mute of front and rear channels\nProgrammable gain (26 dB and 16 dB), independently programmable for the front andrear channels\nLine driver mode supports engine start at a battery voltage as low as 6 V (16 dB andmid-tap voltage 0.25 x VP)\nProgrammable clip detect: 2 %, 5 % or 10 %\nProgrammable thermal pre-warning\nPin STB can be programmed/multiplexed with second-clip detect\nClip information of each channel can be directed separately to pin DIAG or pin STB\nIndependent enabling of thermal- , clip- or load fault information (short across the loador to VP or to ground) on pin DIAG\nLoss-of-ground and open VP safe (minimum series resistance required)\nAll amplifier outputs short-circuit proof to ground, supply voltage and across the load(channel independent)\nAll pins short-circuit proof to ground\nTemperature controlled gain reduction to prevent audio holes at high junctiontemperatures\nProgrammable low battery voltage detection to enable 7.5 V or 6 V minimum batteryvoltage operation\nOvervoltage protection (load-dump safe up to VP = 50 V) with overvoltage pre-warningat 16 V\nOffset detection\n;

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 controlleddiagnostics, including start-up diagnostics. The TDF8541 can operate at a battery voltageas low as 6 V making this amplifier suitable for stop/start-car operation.\nThe 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 withperfect sound quality. The SOI-based BCD process ensures a robust amplifier, wherelatch-up cannot occur, with good separation between the four independent channels, withevery component isolated and without substrate currents.\n
