U490B-MFPG3
U490B-MFPG3 Datasheet
The monolithic integrated bipolar circuit, U490B, is a one-shot power control circuit, designed to control the thyristor which is mainly used in electric stapler devices. The IC is preferred to realize a one-shot phase control, where any phase angle, thus any intensity of the load voltage is adjustable. After successful triggering and the following delay time, an ignition pulse at the output is released. Further triggering is only possible after the delay time elapses.
