ABSTRACT:
A bootstrap logic driver circuit operable from a low voltage power supply includes first and second bipolar transistors coupled between positive and negative voltage supplies and having a collector load comprising a first diode structure. A further transistor coupled between the voltage supplies has a collector load comprising a second diode structure. A bootstrap capacitor coupled between the diode structures stores charge when the circuit is in a first condition and is discharged when the circuit is in a second condition to provide an enhanced drive voltage for an output transistor.
