Layout Considerations
To achieve accurate current sensing, a Kelvin connec-
tion is recommended. The minimum trace width for 1oz
copper foil is 0.02in per amplifier to ensure the trace
stays at a reasonable temperature. However, 0.03in.
per amplifier or wider is recommended. Note that 1oz
copper exhibits a sheet resistance of approximately
530?/square. Small resistances add up quickly in
high-current applications. To improve noise immunity,
connect the resistor-divider to ON close to the device,
and keep traces to V
CC
and GND short. A 0.1礔
capacitor from ON to GND also helps reject induced
noise. Figure 14 shows a layout that addresses these
issues. It is recommended that 2oz copper is used,
particularly as the external MOSFET must be thermally
coupled to the MAX5933_/MAX5947_ to ensure proper
thermal-shutdown operation.
