Positive supply to lower gate driver. Bypass this pin to V
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, which will generally be ground.
Low-side output. Connect to gate of low-side power MOSFET.
No connect.
Exposed pad. Connect to ground or float. The EPAD is electrically isolated from all other pins.
