U490B

One-Shot Phase-Control IC

Description

The monolithic integrated bipolar circuit, U490B, is a voltage is adjustable. After successful triggering and the

one-shot power control circuit, designed to control the following delay time, an ignition pulse at the output is re-

thyristor which is mainly used in electric stapler devices. leased. A further triggering is only possible after the

The IC is preferred to realise a one-shot phase control, elapse of the delay time.
