FEATURES
2.1 General I I I I I I I I I I I I Operates in legacy mode (non I2C-bus) and I2C-bus mode (3.3 V and 5 V compliant) Three hardware-programmable I2C-bus addresses Drive 4 Ω or 2 Ω loads Speaker fault detection Independent short-circuit protection per channel Loss of ground and open VP safe (with 150 mΩ series impedance and a supply decoupling capacitor of 2200 µF maximum) All outputs short-circuit proof to ground, supply voltage and across the load All pins short-circuit proof to ground Temperature-controlled gain reduction to prevent audio holes at high junction temperatures Low battery voltage detection Offset detection This part has been qualified in accordance with AEC-Q100 2.2 I2C-bus mode I DC load detection: open-circuit, short-circuit and load present I AC load (tweeter) detection I During start-up, can detect which load is connected so the appropriate gain can be selected without audio pop I Independently selectable soft mute of front channels (channel 1 and channel 3)...
