Abstract
A current regulator includes a first switch, a second switch, a first current detecting circuit, a second current detecting circuit and a control circuit. Both of the first and second current detecting circuits detect the current of corresponding power route. The control circuit controls the first and the second switches on the route to be turned on or turned off according to detecting signals, and regulates to keep the wiring current in balance.
Claims10
A current regulator, comprising:
- a first switch whose second end provides a power output;
- a second switch whose second end is coupled to the power output;
- a first current detecting circuit, whose input end is coupled to a first power supply and output end is coupled to a first end of the first switch, for detecting a first current and generating a first detecting signal;
- a second current detecting circuit, whose input end is coupled to a second power supply and output end is coupled to a first end of the second switch, for detecting a second current and generating a second detecting signal;
- and
- a control circuit for receiving and comparing the first detecting signal and the second detecting signal to control the first switch and the second switch to be turned on or turned off.
