Description

The TMAG5328 device is a high precision, low-power, resistor adjustable Hall-effect switch sensor operating at low voltage.

The external resistor sets the BOP value for device operation. By following a simple formula, users can calculate the resistor value needed to set up the right BOP value for their designs. The Hysteresis value is fixed and therefore the BRP value is defined as BOP-Hysteresis.

The adjustable threshold feature of the TMAG5328 can help users prototype designs quickly and make last minute modifications in case of unexpected changes, enabling reuse across different platforms.

When the applied magnetic flux density exceeds the BOP threshold, the device outputs a low voltage. The output stays low until the flux density decreases to less than BRP, and then the output drives a high voltage. By incorporating an internal oscillator, the device samples the magnetic field and updates the output at a specified rate. The TMAG5328 features an omnipolar magnetic response.

The device operates from a VCC range of 1.65V to 5.5V, and is packaged in a standard SOT-23-6 package.
