TDF8546JV/N2ZU  NXP

 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 Line driver mode supports engine start at a battery voltage as low as 6 V (16 dB and mid-tap voltage 0.25 VP)  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  Temperature controlled gain reduction to prevent audio holes at high junction temperatures  Programmable low battery voltage detection to enable 7.5 V or 6 V minimum battery voltage operation  Overvoltage protection (load-dump safe up to VP = 50 V) with overvoltage pre-warning at 16 V  Offset detection
