7.1 Overview

The TMAG5328 device is a magnetic sensor with a digital output that indicates when the magnetic flux density threshold has been crossed. The device integrates a Hall effect element, analog signal conditioning, and a low-frequency oscillator that enables ultra-low average power consumption.

While most of the Hall effect sensor have fixed threshold, the TMAG5328 offers an extra pin that allows the user to set up a specific threshold of operation. This pin can either be connected to a resistor or a voltage source. While the value can be set at production, it is also possible to allow dynamic change of either the resistor value or the voltage value to dynamically change the threshold value.

Operating from a 1.65-V to 5.5-V supply, the device periodically measures magnetic flux density, updates the output, and enters into a low-power sleep state.
