Battery Backup Switching IC

GENERAL DESCRIPTION

PACKAGE OUTLINE

The NJU7286 is a battery backup system IC with two regulators,

two voltage detectors, a battery switching system and their

control circuit. It switches the regulator output from main power

supply source to the backup battery when it detects main power

supply drop and also has two voltage detection outputs.

The NJU7286 employs an exclusive sequence on the battery

switching system which reduces the battery operation. Combining

the special sequence and its low operating current, it is well-suited

for battery backup systems of DSC, DVC and other portable

devices. The NJU7286 is available in small and thin packages of

8-lead MSOP (TVSP) and SSOP. And there are four voltage

options available, as follow table.
