(1)
The lowest supply voltage (VDD) at which RESET becomes active. Trise(VDD) ≥ 15s/V.
(2)
The delay time accuracy without external capacitor is the same as that of the TPS3808xxx. This specification is included here for
TPS3808xxx device comparison.
(3)
The combined RESET delay time accuracy from VCT and ICT is ±15%.
