Functional Pin Description
VCC (Pin 1)
DRIVE (Pin 2)
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.
Connect this pin to the gate of an external MOSFET.
This pin provides the drive for the VMEM regulator’s pass
transistor.
