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.
Pin Configurations and Typical Operating Circuit appear at
end of data sheet.

FACTORY-
† 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). Contact
factory for availability and minimum order sizes.
