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.
Features
Low power consumption
Normal operation: 15 A max. (VIN 6 V)
Backup:
2.1 A max.
Voltage regulator
Output voltage tolerance : 2%
Output voltage: Independently selectable in 0.1 V steps in the range of 2.3 V to 5.4 V
Two built-in voltage detectors (CS, RESET)
Detection voltage tolerance: 2%
Detection voltage: Selectable in 0.1 V steps in the range of 2.4 V to 5.3 V (CS voltage detector)
Selectable in 0.1 V steps in the range of 1.7 V to 3.4 V (RESET voltage detector)
RESET release delay: 300 s min.
Switching circuit for primary power supply and backup power supply configurable on one chip
Efficient use of backup power supply possible
Special sequence
Backup voltage is not output when the primary power supply voltage does not reach the initial
voltage at which the switch unit operates.
