Ordering Information (continued)
Note: The first “_ _ ” are placeholders for the output voltage levels of the devices. Desired output voltages are set by the suffix found
in the Output Voltage Suffix Guide (Table 1). The third “_” is a placeholder for the reset threshold accuracy. Desired reset threshold
accuracy is set by the suffix found in the Reset Threshold Accuracy Guide (Table 2). The “_” following the D is a placeholder for the
reset timeout delay time. Desired reset timeout delay time is set by the suffix found in the Reset Timeout Delay Guide (Table 3). For
example, the MAX6481BL30BD4-T has a 3.0V output voltage, 12.5% reset threshold tolerance, and a 1200ms (min) reset timeout
delay. Sample stock is generally available on standard versions only (Table 4). Standard versions require a minimum order incre-
ment of 2.5k units. Nonstandard versions must be ordered in 10k-unit increments. Contact factory for availability.
* Devices are also available in a lead(Pb)-free/RoHS-compliant packages. Specify lead(Pb)-free by substituting a +T instead of a -T
when ordering.
** Future product—contact factory for availability.
