3 Description

The TMAG5133 is an in-plane Hall-effect switch

designed to replace TMR, AMR and Reed switches.

The device is optimized to enable small form factors

across industrial and consumer applications with ultralow

power consumption, wide supply and temperature

ranges.

The TMAG5133 has two unipolar outputs or a single

omnipolar which enable the device to react to external

magnetic fields. When the applied magnetic flux

density through the sensor axis of sensitivity exceeds

the operate point threshold (BOP), the device outputs

a low voltage on the respective pin. The output stays

low until the magnetic flux density decreases to less

than the release point threshold (BRP), after which the

device outputs a high voltage.

To minimize power consumption, the TMAG5133 is

internally duty-cycled. The device has a push-pull

output which eliminates the need for an external

pullup resistor, and is available in an industry standard

X1LGA package.
