HO
High-side NMOS gate drive output. Connect to the gate of the high-side NMOS transistor through a
short, low inductance path.
19
20
HB
High-side driver supply for the bootstrap gate drive. Connect to the cathode of the external bootstrap
diode and to the bootstrap capacitor. The bootstrap capacitor supplies current to charge the high-side
NMOS gate and should be placed as close to controller as possible.
20
22
VIN
Supply voltage input source for the VCC regulator.
EP
Exposed pad of the package. Electrically isolated. Should be soldered to the ground plane to reduce
thermal resistance.
