PCB trace shunt resistor for low cost solution
The figure below shows output characteristics of the device when using
a PCB resistive trace for a low cost solution in replacement for a
conventional shunt resistor. The graph shows the linear rise in voltage
across the resistor due to the PTC of the material and demonstrates
how this rise in resistance value over temperature compensates for the
NTC of the device.
The figure opposite shows a PCB layout suggestion. The resistor
section is 25mm x 0.25mm giving approximately 150mΩ using 1oz
copper. The data for the normalized graph was obtained using a 1A
load current and a 100Ω output resistor. An electronic version of the
PCB layout is available through Diodes applications group.
