General Desc ription
The MAX6332/MAX6333/MAX6334 microprocessor (μP)
supervisory circuits monitor the power supplies in 1.8V
to 3.3V μP 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 V
CC
supply voltage declines
below a preset threshold, keeping it asserted for a pre-
set timeout period after V
CC
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 V
CC
down to 0.7V. The MAX6334 is
guaranteed to be in the correct state for V
CC
down to
1.0V.
The reset comparator in these ICs is designed to ignore
fast transients on V
CC
. 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 V
CC
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.
Typical Operating Circuit and Pin Configuration appear
at end of data sheet.
