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.
