Programable monostable

Started by sbkenn 2 years ago2 replieslatest reply 2 years ago44 views


Is anyone aware of a programmable monostable from about 100nS pulse width, upwards.

Is anyone aware of a MOSFet that incorporates a control for synchronous rectification.  i.e. Switches the main switch on when the parasitic diode is forward biased.  It seems to me that this could easily be achieved with the addition of a DC power pin to supply the control circuit.

Have you given these wonderful little timer solutions some thought?

I use them in all soerts of timer needs with and without an extra fet for open drain needs

Unfortunately, there seem to only work as oscillators, albeit with duty-cycle control.  I want to trigger single pulses, preferably with a digitally programmed pulse width.  I can do it with a PIC, but an off the shelf device is preferable.
