Summation of worst case time base and current measurement sampling errors.
Continuous offset cancellation corrects offset errors in the current measurement system. Individual values reported by the
Current register have a maximum offset of ±0.5 LSb’s (±7.8125V). Individual values reported in the Average Current register
have a maximum offset of ±2 LSb’s (±7.8125V).
Current Gain Error specifies the gain error in the Current register value compared to a reference voltage between IS1 and IS2.
The DS2756 does not compensate for sense resistor characteristics, and any error terms arising from the sense resistor should
be taken into account when calculating total current measurement error.
Achieving the 24 Hour Accumulated Current Error assumes positive offset accumulation blanking is enabled (OBEN bit set) and
can require a one time 3.5s in-system calibration after mounting to the printed circuit board. Variations in temperature and supply
voltage are compensated for by periodic offset corrections performed automatically during Active mode operation.
Voltage offset measurement is with respect to 4.2V at +25°C.
Self heating due to output pin loading and sense resistor power dissipation can alter the Temperature reading from ambient
conditions.
