MAX6307UK25D1-T

P1-P3P4-P6P7-P9P10-P11
General Description
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.

Ordering Information
†
The MAX6306/MAX6307/MAX6309/MAX6310/MAX6312/
MAX6313 are available with factory-set V
CC
reset thresholds from
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.
Pin Configurations and Typical Operating Circuit appear at
end of data sheet.
