NJM2346
VOLTAGE AND CURRENT CONTROL IC
■GENERAL DESCRIPTION
The NJM2346 is a low power operation battery charger IC.
It includes a voltage reference and two operational amplifiers for
voltage and current control needed for a design of secondary circuit
for battery chargers and switching regulators.
Low current consumption design contributes low standby power
required for 1A class battery chargers.
