NOTES
1.
All voltages are referenced to VSS.
2.
See “Ordering Information” section of datasheet to determine 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.
Although the Current Register is large enough to report values higher than 1.8A, internal
compensation for sense resistor process variation and temperature effects can reduce the maximum
reportable current to as low as 1.8A.
8.
Requires in-system calibration by user.
9.
This spec excludes the effects of temperature on the sense resistor. The DS2760 compensates for the
internal sense resistor’s temperature coefficient of 4000 ppm/
°
C to an accuracy of
±
500 ppm/
°
C. The
DS2760 does not attempt to compensate for the characteristics of an external sense resistor. 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.
4 year data retention at 70
°
C.
12.
Typical load capacitance on DC
and CC is 100 pF.
