In the lithium-ion battery charging circuits, needs to solve the PWM signal and systems synthesis control item. Therefore, converting voltage feedback signal by C8051F020 MCU ADC0, the result which ADC0 converts delivers the Programmable Counter Array PCA0 module to realize 16-bit PWM trigger signal to control the charging circuit output. At the same time in producing the PWM signal, Use the ADC0 window detector to realize entering value surpassing range alarm and protection, Also, because 12-bit ADC0 is, therefore, Have carried out a recondition on the PCA0 value in program, have realized PWM control signal output, it's frequency is to set up, cause it's application to further nimble, control accuracy more highly.
