Dear All,
I am using ICM7555 to generate a pulse at about 10us with some pulse which might be shorter. So I followed the monostable design suggested by the figure 3 of datasheet below:
**broken link removed**
The ICM7555 has power consumption of 200 uA.
However I realized that the Discharge FET is short to ground all the time. That means the current will flow thru RA all the time. If RA = 2000ohm. There will be 500uA wasted on such path.
Do you think it is possible for us to reroute like this
Output->RA->C instead of VDD->RA->C
so that the capacitor is charged by the current from the output pin instead of VDD.
Would there be any issue interms of stability?
