3.2 EVM Operation
The TMAG5110-5111EVM features two functionally independent circuits, one for the TMAG5110 and one for the
TMAG5111.
Figure 3-1 shows an overview of the PCB layout. The circuit on the left features the TMAG5110
quadrature output device, and the circuit on the right features the TMAG5111 speed and direction output device.
Section 4 goes over the different operational section blocks of the EVM and their functions and components.
For TMAG5110 each output is a logic high or low based on the latch state of the individual internal Hall sensors.
So, for this case, OUT1 is for the Z-axis sensor and OUT2 is for the Xaxis sensor.
For TMAG5111, as the magnet is rotated, OUT1 will indicated speed and OUT2 will indicate direction. Direction
can be determined by observing whether this output is high or low, and Speed is indicated by the rate of output
transitions.
