Uninterrupted power supply circuit composed of MIC5158 is shown as above. The circuit uses MIC5158 to control the uninterrupted power supply which formed by the source electrode of two N-channel tubes. The source electrodes of the 2 N-channel tubes are connected. This can avoid the current from passing the internal diode of integrated voltage regulator. This kind of low dropout regulator can control the battery switch rapidly. The most critical function of the exchange network line monitor is to the output voltage is lower than the designed limiting voltage when the batterr works online.
