NXP Semiconductors TDF8546
The TDF8546 is one of a new generation of complementary quad Bridge-Tied Load (BTL) audio power amplifiers intended for automotive applications. It has a best efficiency mode with full I2C-bus controlled diagnostics, including start-up diagnostics. The TDF8546 can operate at a battery voltage as low as 6 V making this amplifier suitable for stop/start-car operation.| Part No. | TDF8546 |

FEATURES AND BENEFITS
● Stop/start-car prepared: keeps operating without audible disturbance during engine start at a battery voltage as low as 6 V● New best efficiency mode with patented low switching distortion
● Extreme best efficiency mode (uses information from 4 channels) with 17 % less dissipation for uncorrelated signals compared to 2-channel best efficiency mode.
● 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 NXP Semiconductors TDF8546 I2C-bus controlled 4 ...
