DS2786B
Stand-Alone OCV-Based Fuel Gauge
_______________________________________________________________________________________
3
Note 1: All voltages are referenced to VSS.
Note 2: Offset specified after autocalibration cycle and Current Offset Bias Register = 00h.
Note 3: The DS2786B enters the sleep mode 1.5s to 2.2s after (SCL < VIL) and (SDA < VIL).
Note 4: Timing must be fast enough to prevent the DS2786B from entering sleep mode due to bus low for period > tSLEEP.
Note 5: fSCL must meet the minimum clock low time plus the rise/fall times.
