7.6 Timing Requirements

At 1.7 V ≤ VDD ≤ 5.5 V, CT = MR =  Open, RESET Voltage (V RESET ) = 10 kΩ to VDD, RESET load = 10 pF, and over the operating free-air temperature range of – 40°C to 125°C, unless otherwise noted. Typical values are at TJ = 25°C, typical conditions at VDD = 3.3 V.

tD (MR) MR reset time delay  tD ms
(1) 5% Overdrive from threshold. Overdrive % = [VSENSE - VIT] / VIT; Where VIT stands for VIT-(UV) or VIT+(OV)
(2) tPD measured from threhold trip point (VIT-(UV) or VIT+(OV)) to RESET VOL voltage
(3) Output transitions from VOL to 90% for rise times and 90% to VOL for fall times.
(4) During the power-on sequence, VDD must be at or above VDD (MIN) for at least tSD + tD before the output is in the correct state.
