NJU7287 Datasheet (New Japan Radio) - Battery Backup Switching IC

NJU7287, Battery Backup Switching IC

The NJU7287 is a battery backup system IC with three 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
