Table 2-1 shows the comparison across different device versions. Please note that TPS274C65EVM supports
version AS and BS.
Version AS and BS are using SPI interface. AS has full features sets including LED driver, RCB blocking FET
driver and integrated ADC for digital current, temperature and voltage senses. The BS version is using SPI
communication, but does not have LED driver, RCB blocking FET driver or integrated ADC. Version CP is using
traditional GPIO interface with RCB driver.
A table of the versions of TPS274C65 and considerations that have to be taken can be found in Table 2-2 .
Table 2-2. EVM Considerations Across Silicon Versions
TPS274C65 Version EVM Considerations
AS
Default version populated on EVM. Leave J19, J20, J21, J22 open to enable the
RCB FETs. Make sure R1 and R5 are populated to enable LED driving. For the
rest of the connections, follow desired settings from Connection Descriptions .
BS
Populate J19, J20, J21, J22 to bypass the RCB FETs. Do not populate R1 and
R5 as there is no LED driving capability for this version. For the rest of the
connections, follow desired settings from Connection Descriptions .
