Currently designing a circuit with the MA800 angle sensor with SPI communication. Since we are not planning to use the SSI and MGL/MGH pins, can these be left floating? Thank you
Hello, welcome to the MPS forums!
Since these are data output pins, they should be okay to be left floating if unused.
Just note that the quiescent current of unused pins like this may have a slight increase due to pins potentially acting as antennas and picking up noise and leakage currents. These two factors may lead to increased power consumption. But since these are data lines this should not be drastic but should still be checked if this was a concern for your design.
Hope this helped,
