Microcontroller chip with integrated LCD control module and switching capacitor driver circuit

摘要

The microcontroller 50 chip 51 includes a charge pump with a switching-capacitor 83 that generates a plurality of discrete voltages. The switching-capacitor 83 charging circuit charges the capacitor to generate a continuous charge that can be compensated individually from the capacitor. The LCD driver 173 selectively transmits an individual operating voltage level to activate the LCD 10 according to the state of the external system under the control of the microcontroller 50. [
