The Effect of PCB Layout on ACS704 Electrical Performance
Eight different PC boards were fabricated to characterize the effect of PCB design on the operating junction temperature of the
Hall-effect IC inside of the ACS704. These PC boards are shown in the figure below.

2 oz. Cu on both sides of board
An ACS704 device was soldered onto each PC board before beginning the thermal testing. Thermal management tests
were conducted with the following test conditions:
Tests were conducted at ambient temperature, T
a
= 20
°
C. All tests were conducted in still air.
14 gauge wires were used to connect a power supply to a single PC board. These wires carry the 15 A dc primary current during
the tests.
A 15 A dc primary current was applied to a single PC board containing an ACS704 device. This current flowed from pins 1 and 2
to pins 3 and 4 of the ACS704 package.
A 1 mA current was forced from the GND pin to the VCC pin by a Fluke 179 True RMS Multimeter. This was the only power
applied to pins 5-8 of the ACS704 package during testing.
The voltage required to force the 1 mA current from the GND pin to the VCC pin was measured after applying the 15 A primary
current for approximately 25 minutes. A graph similar to the graph below was used to determine the junction temperature of the
ACS704.
