U2403B Datasheet (TEMIC Semiconductors)

U2403B, Charge Timer

The U2403B is a monolithic, integrated-bipolar circuit which can be used in applications for time-controlled, constant-current charge.

Selection of charge current versus timing is carried out by using the external circuit at Pins 2, 3 and 4.

For high current requirement, an external transistor is re
