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 V BOOST
potential up to 12 volts above V IN . This V BOOST is not
regulated, so its voltage is dependent on the input V DD
voltage and output drive loading requirements. An
internal undervoltage lockout circuit keeps the output in
a low state when V BOOST drops below 7.8 volts. Output
is enabled when V BOOST is above 11.3 volts.
