The MAX6305–MAX6313 CMOS microprocessor (µP)

supervisory circuits are designed to monitor more than

one power supply. Ideal for monitoring both 5V and

3.3V in personal computer systems, these devices

assert a system reset if any of the monitored supplies

falls outside the programmed threshold. Low supply

current (15µA) and a small package suit them for

portable applications. The MAX6305–MAX6313 are

specifically designed to ignore fast transients on

any monitored supply.

These devices are available in a SOT23-5 package,

have factory-programmed reset thresholds from 2.5V to

5.0V (in 100mV increments), and feature four power-on

reset timeout periods. Ten standard versions are avail-

able. Contact the factory for availability of non standard

versions.

Pin Configurations and Typical Operating Circuit appear at

end of data sheet.

Ordering Information continued at end of data sheet.

Standard Versions Table appears at end of data sheet.

† The MAX6306/MAX6307/MAX6309/MAX6310/MAX6312/

MAX6313 are available with factory-set V

2.5V to 5V, in 0.1V increments. Insert the desired nominal reset

threshold (from Table 1) into the blanks following the letters UK.

All parts also offer factory-programmed reset timeout periods.

Insert the number corresponding to the desired nominal timeout

period index following the “D” in the part number (D1 = 1ms min,

D2 = 20ms min, D3 = 140ms min, and D4 = 1120ms min). There

are 10 standard versions with a required order increment of 2,500

pieces. Sample stock is generally held on the standard versions

only (see Standard Versions table). Required order increment is

10,000 pieces for non-standard versions. Contact factory for

availability of non-standard versions. 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.
