ELM77xxxxxC is CMOS dual voltage detector which consists of two comparator circuits watching Vdetn2

(Vdd level) and Vdetn1(Vdet input level) simultaneously and independently. This configuration enables output

to maintain the state of detection even when voltage of the Vdet input level drops to 0V.
