Temperature Compensation
For the 71M6513 (regular accuracy parts), the temperature coefficients TC1 and TC2 are given as constants that represent
typical component behavior (in V/°C
2). TC1 and TC2 allow compensation for variations of the reference voltage to within ±40
PPM/°C.
For the high-accuracy parts, individualized coefficients TC1 and TC2 can be retrieved from the on-chip fuses via TRIMBGA,
TRIMBGB, TRIMM[2:0] (see Section ‘Distinction between 71M6513 and 71M6513H Parts’). For the 71M6513H, TC1 and TC2
allow compensation for variations of the reference voltage to within ±10 PPM/°C
Since TC1 and TC2 are given in V/°C and V/°C
2, respectively, the value of the VREF voltage (1.195V) has to be
taken into account when transitioning to PPM/°C and PPM/°C
2. This means that PPMC = 26.84*TC1/1.195 and
PPMC2 = 1374*TC2/1.195).
Close examination of the electrical specification (see Table 62) for the 71M6513 reveals that the achievable deviation is not
strictly ±40 PPM/°C over the whole temperature range: Only for temperatures for which T-22 > 40 (i.e. T > 62°C) or for which
T-22 < -40 (i.e. T < -18°C), the data sheet states ±40 PPM/°C. For temperatures between -18°C and +62°C, the error should
be considered constant at ±1,600 PPM, or ±0.16%.
Similar considerations apply to the high-accuracy part 71M6513H (see Table 63), where the error around the calibration
temperature should be considered constant at ±600 PPM, or ±0.06%.

Figure 31 and Figure 32 show this concept graphically. The “box” from -18°C to +62°C reflects the fact that it is impractical
to measure the temperature coefficient of high-quality references at small temperature excursions. For example, at +25°C,
the expected error would be ±3°C * 40 PPM/°C, or just 0.012% for the regular-accuracy parts.
The maximum deviation of ±2520 PPM (or 0.252%) for the regular-accuracy parts is reached at the temperature
extremes. If the reference voltage is used to measure both voltage and current, the identical errors of ±0.252% add up to
a maximum Wh registration error of ±0.504%.
The maximum deviation of ±630 PPM (or 0.063%) for the 71M6513H is reached at the temperature extremes. If the
reference voltage is used to measure both voltage and current, the identical errors of ±0.063% add up to a maximum Wh
registration error of ±0.126%.
