From an input signal, and using an unusual current source, this circuit generates a ramp, that is, a voltage that grows linearly up to a certain value, and then falls.
We found this circuit in an 80's Electronic Design. The circuit uses an integrated of the time....
With this circuit (shield) we can control a load from 500 mA to 1 A, depending on the transistor, using a...
The consumption of this circuit is only 50 uA in the standby condition and 4.5 mA when supplying a pulse...
