3-Pin, Ultra-Low-Voltage, Low-Power

µP Reset Circuits

General Description

Features

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.

♦ Ultra-Low 0.7V Operating Supply Voltage

♦ Low 3.3µA Supply Current

♦ Precision Monitoring of 1.8V and 2.5V Power-

Supply Voltages

These devices perform a single function: they assert a

below a preset threshold, keeping it asserted for a pre-

set timeout period after V 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

♦ Power-Supply Transient Immunity

♦ No External Components

♦ 3-Pin SOT23 Package

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.

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.
