The S-8425 Series is a
CMOS IC designed for use in the switching circuits of primary and backup power supplies on a single chip.
It consists of three
voltage regulators, two
voltage detectors, a power supply switch and its controller, as well as other functions.
In addition to the function for switching between the primary and backup power supply, the S-8425 Series can provide microcontrollers with two types of
voltage detection output signals corresponding to the power supply
voltage.
Moreover, adopting a special sequence for switch control enables the effective use of the backup power supply, m...
