Conclusion:
DS3102, Rev A2
The following qualification successfully meets the quality and reliability standards required of all
Maxim products:
Device Description:
A description of this device can be found in the product data sheet. You can find the product data
sheet at http://dbserv.maxim-ic.com/l_datasheet3.cfm.
Reliability Derating:
The Arrhenius model will be used to determine the acceleration factor for failure mechanisms that
are temperature accelerated.
AfT = exp((Ea/k)*(1/Tu - 1/Ts)) = tu/ts
AfT = Acceleration factor due to Temperature
tu = Time at use temperature (e.g. 55°C)
ts = Time at stress temperature (e.g. 125°C)
k = Boltzmann’s Constant (8.617 x 10-5 eV/°K)
Tu = Temperature at Use (°K)
Ts = Temperature at Stress (°K)
Ea = Activation Energy (e.g. 0.7 ev)
The activation energy of the failure mechanism is derived from either internal studies or industry
accepted standards, or activation energy of 0.7ev will be used whenever actual failure mechanisms
or their activation energies are unknown. All deratings will be done from the stress ambient
temperature to the use ambient temperature.
An exponential model will be used to determine the acceleration factor for failure mechanisms,
which are voltage accelerated.
AfV = exp(B*(Vs - Vu))
AfV = Acceleration factor due to Voltage
Vs = Stress Voltage (e.g. 7.0 volts)
Vu = Maximum Operating Voltage (e.g. 5.5 volts)
B = Constant related to failure mechanism type (e.g. 1.0, 2.4, 2.7, etc.)
The Constant, B, related to the failure mechanism is derived from either internal studies or industry
accepted standards, or a B of 1.0 will be used whenever actual failure mechanisms or their B are
unknown. All deratings will be done from the stress voltage to the maximum operating voltage.
Failure rate data from the operating life test is reported using a Chi-Squared statistical model at the
60% or 90% confidence level (Cf).
In addition, Maxim's continuous reliability monitor program ensures that all outgoing product will
continue to meet Maxim's quality and reliability standards. The current status of the reliability monitor
program can be viewed at http://www.maxim-ic.com/TechSupport /dsreliability.html.
The failure rate, Fr, is related to the acceleration during life test by:
Fr = X/(ts * AfV * AfT * N * 2)
X = Chi-Sq statistical upper limit
N = Life test sample size
The calculated failure rate for this device/process is:
Only data from Operating Life or similar stresses are used for this calculation.
The parameters used to calculate this failure rate are as follows:

°C Volts
The reliability data follows. At the start of this data is the device information. The next section is the
detailed reliability data for each stress. The reliability data section includes the latest data available and
may contain some generic data. "*" after DATE CODE denotes specific product data and SEQ No. to
identify specific line items in the report for comments when required.
Failure Rates are reported in FITs (Failures in Time) or MTTF (Mean Time To Failure). The FIT
rate is related to MTTF by:
MTTF = 1/Fr
NOTE: MTTF is frequently used interchangeably w ith MTBF.
