3 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 BOPHysteresis.

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 rate of 20Hz (A1D version) for the lowest

current consumption, or continuously (A1Z version).

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.
