Hi Team,
According to the data sheet, tPD(r) is calculated as follows:
tPD(r)[SEC] = CCT x VCT ÷ ICT + tPD(r)(nom)
*tPD(r) = SENSE (rising) to RESET propagation delay
According to the electrical characteristics table, VCT = 1.23V, ICT = 1.15uA, so 1.23[V] ÷ 1.15[uA] ≒ 1.07[uV/A]
Section 8.3.1 states that when CCT = 26uF, tPD(f) = 30s.
tPD(f) = 26[uF] x 1.07[uV/A] + 25[us,(nom)] ≠ 30[s]
The answers don't match.
Please tell me the correct way to calculate tPD(r).
Best Regards,
