7.6 Timing Requirements

At 1.7 V ≤ V_DD ≤ 5.5 V, CT = MR = Open, RESET Voltage (V_RESET) = 10 kΩ to V_DD, 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 T_J = 25°C, typical conditions at V_DD = 3.3 V.

t_{D ( MR)}	MR reset time delay			t_D		ms

(1) 5% Overdrive from threshold. Overdrive % = [V_SENSE - V_IT] / V_IT; Where V_IT stands for V_IT-(UV) orV_IT+(OV)

(2) t_PD measured from threhold trip point (V_IT-(UV) orV_IT+(OV)) to RESET V_OL voltage

(3) Output transitions from V_OL to 90% for rise times and 90% to V_OL for fall times.

(4) During the power-on sequence, V_DD must be at or above V_{DD (MIN)} for at least t_SD + t_D before the output is in the correct state.
