Abstract
A detection circuit and an electronic device using the detection circuit are provided. The detection circuit includes a fourth branch, a fifth branch and a third energy storage unit. The fourth branch includes multiple fourth switches, and the fifth branch includes multiple fifth switches. A preset electrical signal threshold is sampled and applied to the third energy storage unit by controlling the multiple fourth switches in the fourth branch, and a voltage difference between two detection terminals of a first energy storage unit is sampled and applied to the third energy storage unit by controlling the multiple fifth switches in the fifth branch, to compare the voltage difference between the two detection terminals with the preset electrical signal threshold.
