The MAX6335/MAX6336/MAX6337 microprocessor (µP)

supervisory circuits monitor the power supplies in 1.8V

to 3.3V µP and digital systems. They increase circuit reli-

ability and reduce cost by eliminating external compo-

nents and adjustments. They also feature a debounced

manual-reset input.

These devices perform a single function: they assert a

reset signal whenever the V

below a preset threshold or whenever manual reset is

asserted. Reset remains asserted for a preset timeout

period after V

after manual reset is deasserted. The only difference

among the three devices is their output. The MAX6336

(push/pull) and MAX6337 (open-drain) have an active-

low RESET output, while the MAX6335 (push/pull) has

an active-high RESET output. The MAX6335/MAX6336

are guaranteed to be in the correct state for V

to 0.7V. The MAX6337 is guaranteed to be in the cor-

rect state for V

The reset comparator in these ICs is designed to ignore

fast transients on V

trimmable between 1.6V and 2.5V, in approximately

100mV increments. There are 15 standard versions

available (2500 piece minimum-order quantity); contact

the factory for availability of nonstandard versions

(10,000 piece minimum-order quantity). For space-criti-

cal applications, the MAX6335/MAX6336/MAX6337

come packaged in a 4-pin SOT143.

* These devices are available in factory-set V

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 “US” 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.
