MAX803 Series, NCP803 Series
Detail Operation Description
The MAX803, NCP803 series microprocessor reset
supervisory circuits are designed to monitor the power
supplies in digital systems and provide a reset signal to the
processor without any external components. Figure 2 shows
the timing diagram and a typical application below. Initially
consider that input voltage V CC is at a nominal level greater
than the voltage detector upper threshold ( VTH ). And the
RESET (RESET) output voltage (Pin 2) will be in the high
state for MAX803 and NCP803 devices. If there is an input
power interruption and V CC becomes significantly
deficient, it will fall below the lower detector threshold
(V TH ? ). This event causes the RESET output to be in the low
state for the MAX803 and NCP803 devices. After
completion of the power interruption, V CC will rise to its
nominal level and become greater than the V TH . This
sequence activates the internal oscillator circuitry and
digital counter to count. After the count of the timeout
period, the reset output will revert back to the original state.
