7.3.5 Adjustable Threshold

While most Hall Effect switch sensors have fixed magnetic characteristics, the TMAG5328 offers a wide range of adjustable thresholds. The user can use the "ADJ" pin to set the value of BOP threshold. This pin can be used in two different ways. A resistor or a voltage source can be applied on "ADJ". In both scenarios, the resistor or voltage value will define the position of the BOP. While the BOP can be adjusted, the hysteresis has a fixed value. BRP is therefore defined as BOP-Hysteresis.

An 80-µA current is generated on pin "ADJ" when the part goes into active mode. The device then reads the "ADJ" pin and defines the value of BOP. The TMAG5328 supports adjusting the BOP dynamically. If the "ADJ" pin value is adjusted while the sensor is in sleep mode, the BOP will update at the next active period of the device. Consequently, the maximum time it could take for the BOP to update is equal to the period of magnetic sampling, ts.
