The S-8426A 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 two
voltage regulators, three
voltage detectors, a power supply switch and its controller, as well as other functions.
In addition to the switching function between the primary and backup power supply, the S-8426A Series can provide the micro controllers with three 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 supp...
