Channel 1 HS driver output.

1 UGATE1

A small series resistors helps in reducing device-dissipated power.

Channel 1 HS driver supply.

Connect through a capacitor (100nF typ.) to PHASE1 and provide necessary

2 BOOT1 Bootstrap diode.

A small resistor in series to the boot diode helps in reducing Boot capacitor

overcharge.
