Not internally connected.
Channel 1 HS driver output.
A small series resistors helps in reducing device-dissipated power.
Channel 1 HS driver supply.
Connect through a capacitor (100 nF typ.) to PHASE1 and provide necessary
Bootstrap diode. A small resistor in series to the boot diode helps in reducing
Boot capacitor overcharge.
Not internally connected.
Channel 3 HS driver return path.
It must be connected to the HS3 MOSFET source and provides return path for
the HS driver of channel 3.

Not internally connected.
Channel 2 HS driver return path.
It must be connected to the HS2 MOSFET source and provides return path for
the HS driver of channel 2. Leave floating when using 2 phase operation.
