The Low Consumption Timer Circuit

Published:2011/7/12 2:53:00 Author:Michel | Keyword: Timer Circuit | From:SeekIC

The low consumption timer uses timer IC LM122 and it provides the zero power consumption circuit in two rated cycles.The transistor Q1 stops between the two rated cycles so there is no current consumption.When 5 V or higher triggering pulse arrives and Q1 is connected and it begins to measure time. Timing time is set by the R1 and C1, its range is from a few microseconds to several hours.
