4.3 PCB Layout Recommendations
KSENSA is shared between SEN1 and SEN2, KSENSB is shared between SEN3 and SEN4, KSENSEC
is shared between SEN5 and SEN6, KSENSED is shared between SEN7 and SEN8. To optimize the
accuracy of the measurement, the PCB layout must be done carefully to minimize the impact of PCB trace
resistance. For an example, see the
Layout section of the TPS23881 Type-4 4-Pair 8-Channel PoE PSE
Controller With SRAM and 200 m Ω R
SENSE
data sheet.
