FEATURES
2.1 General I Operates in legacy mode (non I2C-bus) and I2C-bus mode (3.3 V and 5 V compliant) I Three hardware-programmable I2C-bus addresses I Drives 4 Ω or 2 Ω loads I Balanced/symmetrical inputs I Speaker fault detection I Programmable gain (26 dB and 16 dB) also available in legacy mode I Independent short circuit protection per channel I Loss of ground and loss of VP safe (with 300 mΩ series impedance and a maximum supply decoupling capacitor of 2200 µF) I All outputs are short-circuit proof to ground, supply voltage and across the load I All pins are short circuit proof to ground I Temperature-controlled gain reduction to prevent audio holes at high junction temperatures I Low battery voltage detection I Qualified in accordance with AEC-Q100 2.2 I2C-bus mode I DC load detection: open (no load), normal load, line-driver load I AC load (tweeter) detection I Detect which load is connected during start-up to allow the system to be configured to select the gain accordingly (e.g. line-driver mode or normal mode).
