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.
