POWER ON AND OFF TEST CIRCUIT

摘要

A power on and off (on/off) test circuit includes a charging and discharging circuit, a control circuit, and a power circuit. The power circuit provides a voltage to the charging and discharging circuit and the control circuit. When a charging voltage of the charging and discharging circuit is greater than or equal to a preset voltage, the charging and discharging circuit discharges and outputs a first control signal to the control circuit, the control circuit controls the computer to be powered on according to the first control signal; when the charging voltage of the charging and discharging circuit is less than the preset voltage, the charging and discharging circuit is charged and outputs a second control signal to the control circuit, the control circuit controls the computer to be powered off according to the second control signal.
