Hi, I'm working on a breakout board for the MC33926 motor driver.
One of the output pins, SF (Statusflag), is an active-low which will go low when there is a problem with the driver.
In the datasheet it says that the SF should be tied to VDD via a pull-up resistor.
In addition, I want to add a red LED to indicate when there is a problem (when SF goes low).
Here is a screenshot of that part of the circuit:
This is probably really basic, but do I really need the left pull-up resistor? Will the Led and right resistor also function as a pull-up resistor?
