Hi, not sure if this is in the right section, but here goes anyway...
I've done a design using ST's VNQ600AP-E quad high side driver. This device has four independent channels and four analog sense outputs which deliver currents proportional to the outputs currents.
I trying to establish what value for RSENSE I should be using for the analogue sense. I'm using a 10K resistor for RPROT on the same output going into the ADC on a PIC.
Here is the data sheet http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/DATASHEET/CD00044281.pdf
I have played with various resistors from 5K down to 1K, I'd like to use 1K to get a nice range for the ADC but am unsure what effect this will have on the PIC ADC input.
Any help in deciphering the data sheet would be greatly appreciated!
