Overview

U2403B Charge Timer Description 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 recommended in series with the battery.
To protect the IC against high power loss (typically > 140°C), the oscillator is shut down when the reference voltage is switched off (0 V).
The latter also takes place when there is a saturation caused by collector voltage at Pin 1.
When the overtemperature has disappeared and the collector voltage at Pin 1 has exceeded the sup...
