Push-Pull Active-High Reset Output. RESET changes from low to high when the
RESET IN input drops below the 187.4mV reset threshold (referenced to V CC ).
RESET remains high for the reset timeout period after RESET IN exceeds the reset
threshold.

MAX6845 assert a reset signal when the V CC to RESET IN differential falls below
its threshold voltage.
