U490B  
One-Shot Phase Control  
Description  
The monolithic integrated bipolar circuit, U490B, is a After successful triggering and the following delay time,  
one-shot power control circuit, designed to control the an ignition pulse at the output is released. A further trig-  
thyristor which is mainly used in electric stapler devices. gering is only possible after the elapse of the delay time.  
The IC is preferred to realise a one-shot phase control,  
where any phase angle and thus any intensity of the load  
voltage is adjustable.
