4.2.1 TMAG5110 Side

U1 is the TMAG5110 which is a dual Hall latch with a quadrature output. C1 is a bypass capacitor that is placed near the sensor to help mitigate power supply noise and provide current quickly to the device when needed. R1 and R2 are pull up resistors since the device output is open drain. Note that a different resistance can be used for these resistors, based on the system speed and power requirements.

The TMAG5110 outputs can be directly monitored or used with the included test points TP5 and TP6 (for OUT2 and OUT1, respectively). D21 and D22 show the logic state of each output. R3 and R4 are current limiting resistors to control the brightness of the LEDs.
