Uninterruptible power supply circuit diagram composed of MIC5158

Power circuit refers to the circuit design, circuit form and characteristics of the power supply part that provides power to electrical equipment. The power supply includes AC power supply and DC power supply. Power supply circuits can generally be divided into switching power supply circuits, voltage-stabilized power supply circuits, current-stabilizing power supply circuits, power power supply circuits, inverter power supply circuits, DC-DC power supply circuits, protection power supply circuits, etc.

As shown in the figure below, it is an uninterruptible power supply circuit diagram composed of MIC5158. This circuit uses MIC5158 to control two N-channel MOSFETs as switches to form an uninterruptible power supply. The two N-channel MOSFETs are connected source-to-source, thus preventing current from flowing through their own integrated diodes. The low dropout voltage regulator thus constructed can quickly control battery switching. The most critical function of the AC network cable monitor is to ensure that when the battery is still working online, the output voltage is below the designed limit voltage.
