Note 1:

Note 2:

temperature, or current measurements.

Note 3:

Self heating due to output pin loading and sense resistor power dissipation can alter the

reading from ambient conditions.

Note 4:

Although the Voltage Register is large enough to report values larger than 4.75V, the internal

compensation for circuit variations can reduce the maximum reportable voltage to as low as

4.75V.

Note 5:

Voltage offset measurement is with respect to 4.35V at +25°C.

Note 6:

Internal current-sense resistor configuration.

Note 7:

External current-sense resistor configuration.

Note 8:

The Current Register supports measurement magnitudes up to 2.56A using the internal sense-

resistor option and 64mV with the external resistor option. Compensation of the internal

sense-resistor value for process and temperature variation may reduce the maximum

reportable magnitude to 1.9A.

Note 9:

Current offset error null to ±1 LSb typically requires a one time 3.5s in-system calibration by

user.

Note 10: Current gain-error specification applies to gain error in converting the voltage difference at

IS1 and IS2, and excludes any error remaining after the DS2751 compensates for the internal

sense-resistor’s temperature coefficient of 3700ppm/

°C to an accuracy of ±500ppm/°C. The

DS2751 does not compensate for external sense resistor characteristics, and any error terms

arising from the use of an external sense resistor should be taken into account when

calculating total current measurement error.

Note 12: Four year data retention at +70°C.
