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.

† 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.
