Sports Telemetry Device Reliability Calculations


Tps62203 ti 3 3v regulator

C1 = .07

Only 2 inputs, 1 output but still

modestly complex

πT = .24

Digital MOS, assuming at 45C

C2 = .0016

5 pins

πE = 2

Ground fixed assumed

πQ = 10

Commercial part

πL = 1

Out since 2007

λp = .22 fails / 10^6 hours

1/λp= 4545454.5 hours to failure

TPS62203 – TI 3.3v Regulator


Mt29f16g08qaawc nand flash

C1 = .14

Very complex die

πT = .24

Digital MOS, assuming at 45C

C2 = .025

48 pins

πE = 2

Ground fixed assumed

πQ = 10

Commercial part

πL = 1.8

Out since Jan, 2012

λp = .696 fails / 10^6 hours

1/λp= 1436781 hours to failure

**16GB Micron Flash has a min

of 7,992 blocks functional and

a max of 8,192 when shipped

Union battery 063450 1000mah

Capacitor, Electrolytic, Aluminum

λb= .012Base Failure Rate: assumed to be around 40C

πCV= 1 Capacitance Factor: assumed to be 400uF

πE= 2 Environmental Factor: Ground fixed assumed

πQ = 10Quality Factor: Commercial part

λp= λb * πCV * πE * πQ = .24 fails / 10^6 hours

1/ λp = 4166666.7 hours to failure
