8 / 30 page  Temperature Measurement The DS2788 uses an integrated temperature sensor to measure battery temperature with a resolution of 0.125°C. Temperature measurements are updated every 440ms and placed in the Temperature (TEMP) register in two’s complement form. Figure 4 shows the format of the Temperature register. Current Measurement In the ACTIVE mode of operation, the DS2788 continu- ally measures the current flow into and out of the bat- tery by measuring the voltage drop across a low-value current-sense resistor, RSNS. The voltage-sense range between SNS and VSS is ±51.2mV. The input linearly converts peak signal amplitudes up to 102.4mV as long as the continuous signal level (average over the con- version cycle period) does not exceed ±51.2mV. The ADC samples the input differentially at 18.6kHz and updates the Current (CURRENT) register at the com- pletion of each conversion cycle. The Current register is updated every 3.515s with the current conversion result in two’s complement form. Charge currents above the maximum register value are reported at the maximum value (7FFFh = +51.2mV). Discharge currents below the minimum register value are reported at the minimum value (8000h = -51.2mV).
