1. When VS > 16 V the output current limit is reached (triggering embedded internal protections).
2. In legacy mode only low threshold option is available.
3. Saturated square wave output.
4. Voltage ramp on STBY pin:
from 3.3 V to 4.2 V in t ≥ 40 ms.
In case of I2C mode command IB1(D1) = 1 (Mute → Unmute rear channels) and/or IB1(D2) = 1 (Mute → Unmute front
channels) must be transmitted before to start the voltage ramp on STBY pin.
5. Voltage ramp on STBY pin:
from 4.05 V to 3.55 V in t ≥ 40 ms.
In case of I2C mode command IB1(D1) = 0 Unmute → Mute rear channels) and/or IB1(D2) = 0 (Unmute → Mute front
channels) must be NOT transmitted before to start the voltage ramp on STBY pin.
