Battery Backup Switching IC
NJU7286
GENERAL DESCRIPTION
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.
