So, I wanted to create some events in my microchip based on the measurement of a capacitor voltage. The highest charge the cap would see is 300v. So, I thought I would create a voltage divider. With the calculations, R1 and R2 of the divider came to be 59k Ohms and 100 Ohms. This scales down fine for my ADC measurement....but it obviously drains the heck out of the cap I am charging.
Are there better options for this?
The only think I could think to do is put huge resistors in the divider to limit current flow.
