BATTERY BACKUP SWITCHING IC
Rev.3.1_02
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, making this IC ideal for configuring a backup system.
