摘要： An over-current alerting circuit used in a hand held device includes a current sensor module, a photo sensor module and an alerting module. The current sensor module is used for sensing a loading current of the hand held device and outputting a photo signal according to the intensity of the loading current. The photo sensor module is used for generating a driving signal when the intensity of the photo signal is higher than a predetermined intensity. The alerting module is used for performing an alerting action after the driving signal is received. In addition, an over-current alerting method is also disclosed herein.

摘要翻译： 在手持设备中使用的过电流警报电路包括电流传感器模块，光传感器模块和警报模块。 电流传感器模块用于感测手持装置的负载电流，并根据负载电流的强度输出光信号。 光传感器模块用于当光信号的强度高于预定强度时产生驱动信号。 告警模块用于在接收到驱动信号后执行告警动作。 此外，本文还公开了过电流警报方法。
