PCB Layout Considerations
For proper operation of the LTC1646s circuit breaker
function, a 4-wire Kelvin connection to the sense resistors
is highly recommended. A recommended PCB layout for
the sense resistor, the power MOSFET, and the GATE drive
components around the LTC1646 is illustrated in
Figure 15. In Hot Swap applications where load currents
can reach 10A, narrow PCB tracks exhibit more resistance
than wider tracks and operate at more elevated tempera-
tures. Since the sheet resistance of 1 ounce copper foil is
approximately 0.5m&/?/SPAN>? track resistances add up quickly
in high current applications. Thus, to keep PCB track
resistance and temperature rise to a minimum, the sug-
gested trace width in these applications for 1 ounce
copper foil is 0.03" for each ampere of DC current.
In the majority of applications, it will be necessary to use
plated-through vias to make circuit connections from
component layers to power and ground layers internal to
the PC board. For 1 ounce copper foil plating, a general rule
is 1A of DC current per via, making sure the via is properly
dimensioned so that solder completely fills any void. For
other plating thicknesses, check with your PCB fabrication
facility.
