Pin Function
Input supply for gate drivers. Decouple this pin to VSS with a >2.2µF capacitor. Anode
connection to internal bootstrap diode.
No Connect
High-side bootstrap supply. External bootstrap capacitor is required. Connect bootstrap
capacitor across this pin and HS. Cathode connection to internal bootstrap diode.
High-side drive output. Connect to gate of the external high-side power MOSFET.
High-side drive reference connection. Connect to source of the external high-side power
MOSFET. Connect this pin to the bootstrap capacitor.
High-side drive input.
Low-side drive input.
Driver reference supply input. Connected to power ground of external circuitry and to source
of low-side power MOSFET.
Low-side drive output. Connect to gate of the external low-side power MOSFET.
Exposed pad. Connect to VSS.
