Features
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 Ω and 4 Ω 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
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
Over-voltage protection (load-dump safe up to VP = 50 V) with over-voltage pre-warning at 16 V
Offset detection
