NJM2146B
VOLTAGE AND CURRENT CONTROL IC
s 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.
