EPAD
Chip negative supply, generally will be ground.
Low-side output. Connect to gate of low-side power MOSFET.
High-side source connection. Connect to source of high-side power MOSFET. Connect negative side of bootstrap capacitor to this
pin.
High-side output. Connect to gate of high-side power MOSFET.
High-side bootstrap supply. External bootstrap diode and capacitor are required. Connect cathode of bootstrap diode and positive
side of bootstrap capacitor to this pin.
Exposed pad. Connect to ground or float. The EPAD is electrically isolated from all other pins.
