The first switch component is connected between an input voltage and the battery, to charge the battery. The temperature detection unit detects a temperature of the battery, and converts the temperature into a voltage signal. The amplifier is connected to the comparator to amplify the voltage signal and output the amplified voltage signal to the comparator. The comparator is connected to the controller to compare the amplified voltage signal with a reference voltage Vref. The controller is connected to the first switch component to turn off the first switch component to stop charging the battery when the amplified voltage signal is greater than the reference voltage Vref."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Battery protection circuit used in electronic device","description":"A battery protection circuit of an electronic device having a battery includes a first switch component, a temperature detection unit, an amplifier, a comparator, and a controller.
