7.5 Electrical Characteristics

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.

(1) Hysteresis is with respect of the tripoint (V_IT-(UV), V_IT+(OV)).

(2) V_POR is the minimum V_DD voltage level for a controlled output state.

(3) RESET pin is driven low when V_DD falls below UVLO.

(4) V_CT voltage refers to the comparator threshold voltage that measures the voltage level of the external capacitor at CT pin.
