TPS3828: Aging and temperature change of Tout

Part Number: TPS3828


Please tell me about aging deterioration and temperature change of watchdog timeout.

Device: TPS3828 (Time Out: 0.9 ~ 2.5s)
・It was originally supposed to take 0.2s to clear, but due to a software error it took 1.2s.
・No defects in customer board production for 1 year (probably WDT was less than 1.2s)
・3 market defects this year (estimated to be 1.2s or less individuals. Possibility of lot dependence?)
Does Watch Dog Time Out change due to aging (deterioration) or temperature changes?
(Is it correct to assume that there is almost no change due to variation in individual differences?)

Customers should consider market impacts and countermeasures. So I would like you to answer this question.

Best regards,
