General Description
The TC4626/TC4627 are single CMOS high speed
drivers with an on-board voltage boost circuit. These
parts work with an input supply voltage from 4 to 6 volts.
The internal voltage booster will produce a VBOOST
potential up to 12 volts above VIN. This VBOOST is not
regulated, so its voltage is dependent on the input VDD
voltage and output drive loading requirements. An
internal undervoltage lockout circuit keeps the output in
a low state when VBOOST drops below 7.8 volts. Output
is enabled when VBOOST is above 11.3 volts.
