Resistor-adjustable, low-power Hall-effect switch

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.
