PARAMETER
All voltages are referenced to V
Offset specified after auto-calibration cycle and Current Offset Bias Register = 00h.
The DS2786 enters the Sleep mode 1.5s to 2.2s after (SCL < V
Timing must be fast enough to prevent the DS2786 from entering Sleep mode due to bus low for period

This device internally provides a hold time of at least 100ns for the SDA signal (referred to the V
the SCL signal) to bridge the undefined region of the falling edge of SCL.
Filters on SDA and SCL suppress noise spikes at the input buffers and delay the sampling instant.
