Microchip Technology, Inc. Non-Inverting Power CMOS Driver with Voltage Tripler en010682

The TC4626/4627 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. Additional Features Power driver with on Board Voltage Booster Low IDD: < 4mA Small Package: 8-Pin PDIP Under-Voltage Circuitry Fast Rise-Fall Time: < 40nsec @ 1000pF Below-Rail Input Protection
