Linux/UCD9090A: UCD9090A can't detect over-temperature fault/warning

Part Number: UCD9090A

Tool/software: Linux

Hi Support,

We are using UCD9090A on our platform.

When we trigger the over-temperature fault/warning condition, the TEMP bit of STATUS_WORD register is not changed (bit 2 of 79h is 0).

For example, if we set OT_FAULT_LIMIT register 4Fh as 0x8000, OT_WARN_LIMIT register 51h as 0x8000, the TEMP bit 2 of STATUS_WORD register 79h is still 0.

Does UCD9090A support over-temperature fault/warning detection?

Regards, 

Chris
