General Description
The MAX6332/MAX6333/MAX6334 microprocessor (P)
supervisory circuits monitor the power supplies in 1.8V
to 3.3V 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 pre-
set timeout period after VCC has risen above the reset
threshold. The only difference among the three devices
is their output. The MAX6333 (push/pull) and MAX6334
(open-drain) have an active-low RESET output, while
the MAX6332 (push/pull) has an active-high RESET out-
put. The MAX6332/MAX6333 are guaranteed to be in
the correct state for VCC down to 0.7V. The MAX6334 is
guaranteed 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 1.6V and 2.5V, in approximately
100mV increments. There are 15 standard versions
available (2,500 piece minimum-order quantity); con-
tact the factory for availability of nonstandard versions
(10,000 piece minimum-order quantity). For space-criti-
cal applications, the MAX6332/MAX6333/MAX6334
come packaged in a 3-pin SOT23.

Ordering Information
* These devices are available in factory-set VCC reset thresh-
olds from 1.6V to 2.5V, 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.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
Typical Operating Circuit and Pin Configuration appear
at end of data sheet.
