Positive Supply to lower gate drivers. De-couple this pin to Vss (pin 7).
Bootstrap diode connected to HB (pin 2).
High-Side Bootstrap supply. External bootstrap capacitor is required.
Connect positive side of bootstrap capacitor to this pin. Bootstrap diode is on-chip.
High-Side Output. Connect to gate of High-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 input.
Low-Side input.
Chip negative supply, generally will be ground.
Low-Side Output. Connect to gate of Low-Side power MOSFET.
