Summary:The utility model provides a protection circuit, includes: comparison circuit, comparison circuit acquires converting circuit's measuring voltage, comparison circuit still is based on measuring voltage and reference voltage output compare signal work as measuring voltage is greater than during reference voltage, the comparison signal of comparison circuit output high level, control circuit, including the controller, the controller is including selecting the pin, control circuit connect in comparison circuit is when receiving during the comparison signal of high level, control circuit will thelevel of selecting the pin becomes the low level, so that controller not output pulse signal is given converting circuit. The utility model also provides a battery charging outfit that has this protection circuit. Above -mentioned protection circuit and have battery charging outfit of this protection circuit can be under the condition of overflowing, the controller is output pulse signal not then,the vary voltage circuit
