General Description
The MAX6800/MAX6801/MAX6802 microprocessor (P)
supervisory circuits monitor the power supplies in 2.85V
to 5.0V P and digital systems. They increase circuit
reliability and reduce cost by eliminating external com-
ponents and adjustments.
These devices perform a single function—they assert a
reset signal whenever the VCC supply voltage declines
below a preset threshold, keeping it asserted for a preset
timeout period after VCC has risen above the reset
threshold. The only difference among the three devices
is their output. The MAX6801 (push/pull) and MAX6802
(open-drain) have an active-low RESET output, while the
MAX6800 (push/pull) has an active-high RESET output.
The MAX6800/MAX6801 are guaranteed to be in the cor-
rect state for VCC down to 0.7V. The MAX6802 is guaran-
teed to be in the correct state for VCC down to 1.0V.
The reset comparator in these ICs is designed to ignore
fast transients on VCC. Reset thresholds are factory-
trimmable between 2.63V and 4.80V, in approximately
100mV increments. These devices are available with a
1ms (min), 20ms (min), or 100ms (min) reset pulse
width. Ideal for space-critical applications, the
MAX6800/MAX6801/MAX6802 come packaged in a 3-
pin SOT23. For a lower threshold voltage version, see
the MAX6332/MAX6333/MAX6334.

Ordering Information
*These devices are available in factory-set VCC reset thresh-
olds from 2.63V to 4.80V, in approximately 0.1V increments.
Choose the desired reset threshold suffix from Table 1 and
insert it in the blanks following “UR” in the part number.
Factory-programmed reset timeout periods are also available.
Insert the number corresponding to the desired nominal reset
timeout period (1 = 1ms min, 2 = 20ms min, 3 = 100ms min) in
the blank following “D” in the part number. There are 15 stan-
dard versions with a required order increment of 2500 pieces.
Sample stock is generally held on the standard versions only
(see Selector Guide). Contact the factory for availability of non-
standard versions (required order increment is 10,000 pieces).
All devices available in tape-and-reel only.
Typical Operating Circuit and Pin Configuration appear
at end of data sheet.
