HIP6021A Datasheet (Intersil Corporation) - Advanced PWM and Triple Linear Power Controller

HIP6021A, Advanced PWM and Triple Linear Power Controller

VCC (Pin 28) 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.

the soft-start capacitor, disabling all the outputs.
