Internal current-sense resistor configuration.
External current-sense resistor configuration.
Test conditions are PLS = 4.1V, V
Self-heating due to output pin loading and sense resistor power dissipation can alter the reading from ambient conditions.
Voltage offset measurement is with respect to V
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 can reduce the
maximum reportable magnitude to 1.9A.
Current offset error null to ±1LSB typically requires 3.5s in-system calibration by user.
Current gain error specification applies to gain error in converting the voltage difference at IS1 and IS2, and excludes any error
remaining after the DS2762 compensates for the internal sense resistor’s temperature coefficient of 3700ppm/°C to an accuracy
of ±500ppm/°C. The DS2762 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.
Typical value for t
for -20°C to +70°C.
Four-year data retention at +70°C.
Typical load capacitance on DC and CC is 1000pF.
Error at time of shipment from Dallas Semiconductor is 3% max. Board mounting processes may cause the current gain error
to widen to as much as 10% for devices with the internal sense resistor option. Contact factory for on-board recalibration
procedure for devices with the internal sense resistor option to improve accuracy.
