36V20 5v current usage

I have a 36V20cs motor driver and the manual says that the +5v outputs for the current sensor can only supply a few milliamps. I looked the circuit over and the driver chip has its numbers scrapped off so I cant find a data sheet to find out how many milliamps I can use. I want to use it to power a hall effect sensor to a arduino input. the most power it uses is the 10Ma led. It measures 11Ma. Will it burn up the driver chip? Will it affect the current output reading? any help please.


We recommend using a separate 5V supply. The internal regulator is primarily exposed to provide a convenient means of pulling up logic pins, and pulling too much current from that pin can permanently damage the board.
