Hi
I need to have only two channels of isolation, one for WS2812 Fast LED signals and the other for a PWM signal to a motor. The motor is variable Hz to demo the effect of going too high and too low on the controller.
Using the Teensy 3.5 but may switch to the 4.1 later.
So I think I need a pretty fast Isolator. I found this HCPL 9030 for the two channels. https://docs.broadcom.com/doc/AV02-0137EN
Can anyone point me in the right direction as to how I should make this work? Is it powerful enough to drive the LEDs? They are 1m away and only 60 of them. The Mosfet Driver chip TTL at 5v and has inbuilt resistors.
I think I dont need a resistor on the input, but still need 100k on the output for the LEDs.
