as an adjustable voltage monitor, general-purpose
comparator, or digital-level translator.
The MAX6714 quad voltage monitor/reset offers one
fixed input with internal timing for μP reset, three power-
fail comparators, and a manual reset input ( MR ). RESET
asserts low when V CC drops below its threshold or MR is
driven low. Each of the three power-fail inputs connects
directly to one of the comparator inputs.
When any input is higher than the threshold level, the
output is high. The output goes low as the input drops
below the threshold voltage. The undervoltage lockout
circuitry remains active and all outputs remain low with
V CC down to 1V (Figures 1 and 2).
Applications Information
Hysteresis
When the voltage on one comparator input is at or near
the voltage on another input, ambient noise generally
causes the comparator output to oscillate. The most
common way to eliminate this problem is through hys-
teresis. When the two comparator input voltages are
equal, hysteresis causes one comparator input voltage
to move quickly past the other, thus taking the input out
of the region where oscillation occurs. Standard com-
parators require hysteresis to be added through the
use of external resistors. The external resistive network
usually provides a positive feedback to the input in
order to cause a jump in the threshold voltage when
output toggles in one direction or the other. These
