Hi everyone....
Can this simple circuit be used to add extra protection to a otherwise not fully managed LED driver.
Originally the PWM was driving the FET direct, the 0.1 ohm also added..
Want to prevent my existing "expensive, aka bad choice" driver's to make a wrong decision again.
I thrown together a test on my desk and looks like works, I can set the max current with R1 even if the PWM stops on the full on state.
I need to make a driver for 32ch LED lighting system controlled by 32 PWM channel![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
