PCB Layout Considerations
Because of the low values of the sense resistors used with the
MIC2584/85 controllers, special attention to the layout must
be used in order for the devices circuit breaker function to
operate properly. Specifically, the use of a 4-wire Kelvin
connection to accurately measure the voltage across R
SENSE
is highly recommended. Kelvin sensing is simply a means of
making sure that any voltage drops in the power traces
connecting to the resistors does not get picked up by the
traces themselves. Additionally, these Kelvin connections
should be isolated from all other signal traces to avoid
introducing noise onto these sensitive nodes. Figure 14
illustrates a recommended, multi-layer layout for the R
SENSE
,
Power MOSFET, timer(s), and feedback network connec-
tions. The feedback network resistor values are selected for
a 12V application. Many hot swap applications will require
load currents of several amperes. Therefore, the power (V
CC
and Return) trace widths (W) need to be wide enough to allow
the current to flow while the rise in temperature for a given
copper plate (e.g., 1oz. or 2oz.) is kept to a maximum of
10癈 ~ 25癈. Also, these traces should be as short as
possible in order to minimize the IR drops between the input
and the load. For a starting point, there are many trace width
calculation tools available on the web such as the following

Finally, the use of plated-through vias will be needed to make
circuit connections to power and ground planes when utilizing
multi-layer PC boards.
