ABSTRACT:
A scan mode is used in a voltage detection circuit. An oscillator in the circuit is always on and a system including the voltage detection circuit detects various abnormal conditions, such as overcharging, overdischarging and overcurrent one by one for some clocks. To reduce the power consumption, the voltage detection circuit is turned on only once for several clocks. The on-time is very short and lasts about only one tenth of a clock cycle time. In other times, the voltage detection circuit is turned off to save power consumption.
