Charge Timer

Description

The U2403B is a monolithic, integrated-bipolar circuit (typically > 140°C), the oscillator is shut down when the

which can be used in applications for time-controlled, reference voltage is switched off (0 V). The latter also

constant-current charge. Selection of charge current takes place when there is a saturation caused by collector

versus timing is carried out by using the external circuit voltage at Pin 1. When the overtemperature has

at Pins 2, 3 and 4. For high current requirement, an disappeared and the collector voltage at Pin 1 has

external transistor is recommended in series with the exceeded the supply voltage (V > V ), charge time

battery. To protect the IC against high power loss operation continues (see flow chart in figure 3).
