The Tsample value doesn't reach the published value (between 0.3 and 0.5 s, and from my measurements between 0.3 and 0.35 s) until Vstore reaches the EOC threshold. Before, it is just around 80 ms. Once EOC is reached and when Vstore decreases again the published range is achieved, but when Vstore decreases below the UVP threshold, the value of 80 ms shows again and it keeps until the EOC threshold is reached again. I tested this with 2 different chips. This behaviour is not stated in the datasheet.
