TDF8541
description
The TDF8541 is one of a new generation of plementary 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 plementary 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 ponent 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 I2C-bus) or I2C-bus modes (3.3 V and 5 V pliant)
- Four hardware-programmable...
