BOOT2
Channel 2 bootstrap capacitor pin. This pin supplies the high side driver. Connect through a
capacitor to the PHASE2 pin and through a diode to Vcc (cathode vs. boot).
Channel 2 high side gate driver output.
This pin is connected to the Source of the upper mosfet and provides the return path for the
high side driver of channel 2.
Channel 2 low side gate driver output.
Power ground pin. This pin is common to both sections and it must be connected through the closest
path to the low side mosfets source pins in order to reduce the noise injection into the device.
