ELECTRICAL CHARACTERISTICS: 2-WIRE INTERFACE
(2.5V ≤ V
Note 1: All voltages are referenced to GND.
Note 2: SDA, SCL = GND; EO, SEO idle.
Note 3: External time base on EO pin must meet this specification.
Note 4: The MAX17040/MAX17041 enter Sleep mode 1.75s to 2.5s after (SCL < V
Note 5: f
Note 6: The maximum t
Note 7: This device internally provides a hold time of at least 75ns for the SDA signal (referred to the V
Note 8: Filters on SDA and SCL suppress noise spikes at the input buffers and delay the sampling instant.
Note 9: C
Note 10: Applies to 8-pin TDFN-EP package type only.
