ALARM CIRCUIT FOR ELECTRONIC DEVICE |
| 摘要 |
An alarm circuit for electronic device includes a detection unit, a signal conversion circuit, and an alarm control circuit. The detection unit is configured to detect a working status of an electronic device, and output a control signal of a first voltage level when the detection circuit determines the presence of smoke in the electronic device. The signal conversion circuit is configured to receive the control signal of the first voltage level, and convert the control signal of the first voltage level to an alarm signal of a first voltage level. The alarm control circuit is configured to receive the alarm signal of the first voltage level and transmit an alarm. |
