FUNCTIONAL DESCRIPTION

FUNCTIONAL PIN DESCRIPTION

CHARGE PUMP BUCKET CAPACITOR (C1L, C1H,

C2L, C2H)

These two pairs of pins, the C1L and C1H and the C2L and

C2H, connect to the external bucket capacitors required by

the internal charge pump. The typical value for the bucket

capacitors is 0.1

µF.

GATE DRIVER OUTPUT (GOUT)

The GOUT output pin provides a level-shifted, high-side

500 pF.

CONTROL CIRCUIT POWER SUPPLY (VDD)

The VDD pin carries the 5.0 V supply voltage and current

into the logic sections of the IC. VDD has an undervoltage

threshold. If the supply voltage drops below the undervoltage

threshold, the output power stage switches to a tri-state

condition. When the supply voltage returns to a level that is

above the threshold, the power stage automatically resumes

normal operation according to the established condition of

the input pins.
