Configuration pin:
0: normal operation
1: single BTL (mono) mode, join the pins OUT1A to OUT1B and
OUT2A to OUT2B (if IN1A is joined to IN1B and IN2A to IN2B)
Standby (power down):
0: low power consumption mode
1: normal operation
High impedance control:
0: all power amplifiers in high-impedance state
1: normal operation
Fault advisor:
0: fault detected (short circuit or thermal)
1: normal operation
Thermal warning advisor:
0: junction temperature = 130 °C
1: normal operation
Input of half bridge 1A
Input of half bridge 1B
Input of half bridge 2A
Input of half bridge 2B
5-V regulator referred to +VCC
Signal positive supply
Exposed pad up
1. The pin is open collector. To have a high logic value it needs to be pulled up by a resistor.
