(5)

Output or reference voltage temperature coefficient is defined as the worst-case voltage change divided by the total temperature range.

(6)

Comparator thresholds are expressed in terms of a voltage differential equal to the nominal reference voltage (measured at

go low when the output drops by 95 mV

varied), with the low-output warning occurring at 6% below nominal (typ) and 7.7% (max).
