Controlling Proportional valves using PWM
hii...i am relatively newbie to electronics..
i have this circuit which works fine..i have attached circuit here...
the circuit has outputs CH_P and CH_N across which proportional valve (Burkert 2824) is connected
there is a low side current sensing, but i am required to change the circuit to high side sensing., and i am planning to use LT6101 which has a sense amplifier and a comparator.
could anyone explain me the working of this circuit please.
In this cicuit, PWR is 24V, PWM is from FPGA, I_SET value is coming from a DAC, I_DIAG is a current diagnosis signal.
If i want to use this circuit for high side measurement, how can i do that...?
Thanks for the replies in advance...!
cheers
