使用PIC14C000实现铅酸电池充电器

The PIC14C000 comes with several peripherals specif-
ically aimed at the battery market. The programmable
reference and onboard comparators are useful for cre-
ating charge control circuits, while the analog-to-digital
(A/D) converter can monitor the charge state to prevent
overcharge. The control software is written in “C” for
maintainability and transportability. Where necessary,
in line assembly is used.

Charge current is controlled by a comparator and pro-
grammable reference onboard the PIC14C000. The
INTRODUCTION other side of the comparator is fed by the voltage
across a sense resistor. The output of the comparator
