Additional thermal information is available on the Allegro website.

The Allegro evaluation board has 1500 mm of  oz. copper on each side, connected to pins 1 and , and to pins 3 and 4, with thermal vias connect-
ing the layers. Performance values include the power consumed by the PCB. Further details on the board are available from the Frequently Asked
Questions document on our website. Further information about board design and thermal performance also can be found in the Applications Informa-
tion section of this datasheet.

RθJA values shown in this table are typical values, measured on the Allegro evaluation board. The actual thermal performance depends on the actual
application board design, the airflow in the application, and thermal interactions between the sensor and surrounding components through the PCB and
the ambient air. To improve thermal performance, see our applications material on the Allegro website.
