ACS704ELC015-DS, Rev. 2
ACS704ELC-015
The results of the testing are shown in the following table.
Improved PC Board Designs
The eight PC boards in the figure above do not represent an ideal PC board for use with the ACS704. The ACS704 evaluation
boards, for sale at the Allegro Web site On-Line Store, represent a more optimal PC board design (see photo below). On the
evaluation boards, the current to be sensed flows through very wide traces that were fabricated using 2 layers of 2 oz. copper.
Thermal management tests were conducted on the Allegro evaluation boards and all tests were performed using the same test
conditions described in the bulleted list above. The results for these thermal tests are shown in the table below. When using
the Allegro evaluation boards we see that even at an applied current of 20 A the junction temperature of the ACS704 is only
~30 degrees above ambient temperature.
