The EVM user guide (www.ti.com/.../sbvu048.pdf) states that the R5, R6, and R7 are rated at 0.25W and that the EVM can supply 55mA in the full-bridge configuration.
0.25/(280)^2 = 29mA. That will mean that the board can not source more than 29mA in both configurations (half of full-bridge). Is that right?
The user guide however states that the board can operate at full-bridge at 55mA.
Therefore the resistors should be rated at 1W given that .055^2 * 280 = 0.847W.
Would you please clarify?
