PCB Layout Considerations
For proper operation of the LTC4244’s circuit breaker,
4-wire Kelvin sense connections between the sense resis-
tor and the LTC4244’s 5V

and 5V
SENSE
pins and 3.3V
IN
and 3.3V
SENSE
pins are strongly recommended. The PCB
layout should be balanced and symmetrical to minimize
wiring errors. In addition, the PCB layout for the sense
resistors and the power MOSFETs should include good
thermal management techniques for optimal device power
dissipation. A recommended PCB layout for the sense
resistor, the power MOSFET and the GATE drive compo-
nents around the LTC4244 is illustrated in Figure 15. In Hot

Swap applications where load currents can be 10A, nar-
row PCB tracks exhibit more resistance than wider tracks
and operate at more elevated temperatures. Since the
sheet resistance of 1 ounce copper foil is approximately
0.45m
/
o
, track resistance and voltage drops add up
quickly in high current applications. Thus, to keep PCB
track resistance, voltage drop and temperature to a mini-
mum, the suggested 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
