I have 555(NE555N to be exactly) timer controlled via 5 pin(control voltage, if NC it has 2/3 of Vcc)
It is used for soft-start dc motor.
Now it has 220uF cap connected, but it charges fast in beginning and slow at the end. yes, yes i know that all cap's does the same.
I need simple solution for slow charging in begining and fast at the end, or linear at least, is it possible without any chips?
btw, i already know about simple small current source for linear charging, but i cannot fit in my circuit. it requires external supply line, i would like to use those 2/3 of Vcc that 5th pin has.
Thanks for any comments
