In addition to its function to supply the power to these devices, it has a function to switch the source of power to the primary or secondary backup battery when the power supply voltage drops below a predetermined level. Also, it outputs a reset signal when the power supply turns on or off or when a fault occurs in the power supply. Ideally designed as a single-chip IC for power supply control, the MB3790 consumes only a minimal current and comes in a thin-type package.
