Electrical Characteristics

At 1.7 V ≤ VDD ≤ 5.5 V, CT = MR =  Open, RESET Voltage (VRESET) = 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.

Hysteresis is with respect of the tripoint (VIT-(UV), VIT+(OV)).
VPOR is the minimum VDD voltage level for a controlled output state.
RESET pin is driven low when VDD falls below UVLO.
VCT voltage refers to the comparator threshold voltage that measures the voltage level of the external capacitor at CT pin.
