Hey
The LTC2239's mode-pin has 4 thresholds (0, 1/3Vdd, 2/3Vdd, Vdd).
Please advise me the tolerance of these thresholds.
regards.

Hi INON
Thanks for your interest in LTC2239.
The datasheet does not explicitly state the tolerance for these thresholds. However, mode-pin thresholds are typically designed to fall within a certain percentage of VDD, often around ±10%. To ensure reliable operation, it’s best to validate on hardware by slowly sweeping the mode voltage and observing the transition points with an oscilloscope.
Thanks for the clarification.
I’m trying to make sure the mode selection is solid across temperature, supply variation, and production spread. Since the datasheet doesn’t give min/max thresholds, do you have any characterized data, typical curves, or internal limits for the MODE pin comparators? Even a rough typical range would help with margining.
If there’s no characterization data available, can you confirm that the ±10% guideline is what you recommend designing around?
Thanks,
Inon
