Other Parts Discussed in Thread: TMP302
Hi there
We are looking at using the TMP302C in an application providing thermal (over temperature) safety protection - its very attractive for this due to its precise temperature accuracy. But, I can’t find any information relating to the reliability/robustness of the part from an electrical safety perspective. Is there any additional data or qualification reports for this part which could be used e.g. to supplement an electrical safety assessment? For instance, the probability of the switch not activating at/above the set temperature? I’ve got the MTBF/FIT figure from TI website, but I’m not sure if the FIT for the process is directly relevant to a safety analysis.
Phrasing the question another way, is the TMP302 intended to perform “safety” function for protection of personnel or equipment?
Is there any literature available about the “benefits” of the Q1 part, other than operating temperature (AEC-Q100 grade 1) and ESD tolerance (HBM/CDM)?
(Is it related to the 100% production test coverage of certain specifications at +25C?)
Is there any specific information available about the “100%” test coverage mentioned on the datasheet, i.e. is that relating to parameters which affect the operation of the switch (such as accuracy/bias current etc)?
thanks and regards
Lachlan
