The PS810 A/D converter measures current, voltage and temperature and integrates the current over time to calculate State-Of-Charge. Cell voltage is measured with a direct connection to the battery cell without requiring an external voltage divider. Using an external sense resistor, current is monitored during both charge and discharge and is integrated over time using the on- chip oscillator as the time base. Temperature is measured from the on-chip temperature sensor or an optional external thermistor. Voltage, current and temperature can be calibrated for accuracy over the operational range. The A/D converter performs sampling using a 32 kHz clock.
Hardware Features
`Highly accurate fuel gauge for single cell Li Ion applications
`Algorithms are implemented using an embedded PIC18 low-power microcontroller with 16-bit instruction set
`Reports current, voltage and temperature utilizing a programmable 8 to15-bit + sign, sigma-delta A/D
`Host communication accomplished through an industry standard SMBus interface or an alternative single pin serial interface
`I/O pins are available to provide functions such as digital GPIO, coin cell voltage measurement and thermistor input
`Integrated thermistor and regulator minimize external components
`Embedded fuel gauge algorithms and application specific parameters are stored in a 4K x 16 Flash memory
`512 bytes of RAM are available for temporary storage of battery parameters
Software Features
`Provides battery status, such as average time to empty, relative State-Of-Charge and battery State-Of-Health
`In-system offset calibration compensates for offset error in current measurement
