VCC (Pin 1) Provide a 12V bias supply for the IC to this pin. This pin also provides the gate bias charge for all the MOSFETs controlled by the IC. The voltage at this pin is monitored for Power-On Reset (POR) purposes. DRIVE (Pin 2) Connect this pin to the gate of an external MOSFET. This pin provides the drive for the FBVDDQ regulator’s pass transistor. |
