NOTES
1)
All voltages are referenced to V
SS
.
2)
See the
Ordering Information
section to determine the corresponding part number for each V
OV
value.
3)
Internal current-sense resistor configuration.
4)
External current-sense resistor configuration.
5)
Self-heating due to output pin loading and sense resistor power dissipation can alter the reading from
ambient conditions.
6)
Voltage offset measurement is with respect to V
OV
at +25°C.
7)
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.
8)
Current offset error null to ±1LSB typically requires 3.5s in-system calibration by user.
9)
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.
10)
Typical value for t
ERR
is at 3.6V and +25 C.
11)
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.
