2 Compatibility Across Silicon Versions

Table 2-1 Device Comparison Table
Device Version Part Number Interface Reverse Current Blocking (RCB) Integrated LED Driver Integrated ADC Fault Diagnosis
AS TP274C65AS SPI Yes Yes Yes Global fault output and single channel information available through SPI
BS TP274C65BS SPI No No No Global fault output and single channel information available through SPI
CP TP274C65CP GPIO Yes No No Per channel fault output

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 VersionEVM Considerations
ASDefault 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.
BSPopulate 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.
