4 / 21 page DS2786 Standalone OCV-Based Fuel Gauge 4 of 21 Note 1: All voltages are referenced to VSS. Note 2: Offset specified after auto-calibration cycle and Current Offset Bias Register = 00h. Note 3: The DS2786 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 DS2786 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. Note 6: The maximum tHD:DAT has only to be met if the device does not stretch the LOW period (tLOW) of the SCL signal. Note 7: This device internally provides a hold time of at least 100ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the undefined region of the falling edge of SCL. Note 8: Filters on SDA and SCL suppress noise spikes at the input buffers and delay the sampling instant. Note 9: CB—total capacitance of one bus line in pF. Figure 1. 2-Wire Bus Timing Diagram PIN DESCRIPTION PIN NAME FUNCTION 1 AIN1 Aux Voltage Input Number 1 2 AIN0 Aux Voltage Input Number 0 3 SCL Serial Clock Input. Input only 2-wire clock line. Connect this pin to the clock signal of the 2-wire interface. This pin has a 0.2µA typical pulldown to sense disconnection. 4 SDA Serial Data Input/Output. Open drain 2-wire data line. Connect this pin to the clock signal of the 2-wire interface. This pin has a 0.2µA typical pulldown to sense disconnection. 5 SNS Current-Sense Input. Connect to the handset side of the sense resistor. 6 VSS Device Ground. Connect to the battery side of the sense resistor. 7 VPROG EEPROM Programming Voltage Input. Connect to external supply for production programming. Connect to VSS during normal operation. 8 VOUT Voltage Out. Supply for Aux Input Voltage Measurement Dividers.
