NJM2146B
VOLTAGE AND CURRENT CONTROL IC
■ GENERAL DESCRIPTION
The NJM2146B is a voltage and current control IC which
contains single-supply low offset voltage OP-AMP (2mV
max.), low operating OP-AMP, and precision voltage
reference. It is suitable for battery charger, second controller
of switching regulator systems, and other battery systems.
