5/13/2011 PRODUCT RELIABILITY REPORT FOR DS1343 Maxim Integrated Products 4401 South Beltwood Parkway Dallas, TX 75244-3292 Prepared by: Don Lipps Manager, Reliability Engineering Maxim Integrated Products 4401 South Beltwood Pkwy. Dallas, TX 75244-3292 Email: don.lipps@maxim-ic.com ph: 972-371-3739 Rev B, 1/3/08 Conclusion: The following qualification successfully meets the quality and reliability standards required of all Maxim products: DS1343 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. 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. 55C) ts = Time at stress temperature (e.g. 125C) 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). 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 Rev B, 1/3/08 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 with MTBF. The calculated failure rate for this device/process is: FAILURE RATE: MTTF (YRS): 15252 FITS: 7.5 DEVICE HOURS: 122423091 FAILS: 0 Only data from Operating Life or similar stresses are used for this calculation. The parameters used to calculate this failure rate are as follows: Cf: 60% Ea: 0.7 B: 0 Tu: 25 C Vu: 5.5 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.
