Abstract

A detection and protection circuit includes: a comparator, six resistors, and two diodes. A first resistor is connected to a second resistor. The second resistor () is grounded. A positive input end, a negative input end, a power supply end, a ground end, and an output end of the comparator are connected to a third resistor, a fourth resistor, a power management device power supply pin, the ground, and a main controller. The other end of the third resistor is connected between the first resistor and the second resistor. The other end of the fourth resistor is connected to the first resistor. A first power supply is connected between the fourth resistor and the first resistor. A fifth resistor is connected to a sixth resistor. The sixth resistor () is grounded. The other end of the fifth resistor is connected to the main controller.
