All voltages are referenced to V SS .
See the Ordering Information section to determine the corresponding part number for each V OV value.
Internal current-sense resistor configuration.
External current-sense resistor configuration.
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 OV at +25°C.
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 DS2761 compensates for the internal sense resistor’s temperature coefficient of 3700ppm/ ° C to
an accuracy of ± 500ppm/ ° C. The DS2761 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 ERR is at 3.6V and +25 ° C.
Four year data retention at +70 ° C.
12) Typical load capacitance on DC and CC is 1000pF.
13) Test conditions are PLS = 4.1V, V DD = 2.5V. Maximum current for conditions of PLS = 15V,
V DD = 0V is 10mA.
14) 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.
