Hello there,
i'm currently testing a design for peak and hold control for a solenoid. The circuit is this :
when i probe the shunt resistor (the pink graph) i get this result :
the yellow is the comparator output and blue is the microcontroller signal. the high voltage is from boost converter. The problem is that i don't get perfectly regulated signal like this
the current drops to zero when the comparator turns off, which it shouldn't happen. Any advice?
Thanks in advance.
