TPS389006-Q1: TPS389006-Q1 Fault information

Part Number: TPS389006-Q1
Other Parts Discussed in Thread: TPS389387EVM,

Hello, 

I am using the TPS389006-Q1 with the TPS389387EVM Joint Evaluation Module and I have the following flag error inside the following registers:


INT_VENDOR (0x24): 7F
TEST_INFO (0x31): 7F

Is it possible to know what could cause these errors?

Best regards

  • Hello, 

    A value of 0x7F would mean that all faults reported in registers 0x24 and 0x31 have been flagged. Is this behavior seen on every power up? Can these faults be cleared by performing a 1 to clear on the registers? Are the parts used in this test the parts provided with the TPS389387EVM or have they been replaced with another variant? 

    Regards,
