PS810
Li Ion Single Cell Fuel Gauge
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 ADC
• 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 temperature sensor 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
Package Features
• 16-pin QFN package or 14-pin TSSOP package
• -20°C to +85°C operating temperature range
1.0 PRODUCT OVERVIEW
The PS810 is a fuel gauge for one-cell Li Ion or Li Poly-
mer applications. The device provides the host and the
system user with critical battery information, such as
voltage, current, temperature, run time, State-Of-Charge
and State-Of-Health. This information is available
through an industry standard SMBus or an alternative
Single Pin Serial interface. Advanced fuel gauge
algorithms are stored in on-board Flash memory and
executed by the industry recognized PIC18 micro-
controller. These algorithms include compensation
factors which optimize the performance of the battery for
a specific application and operating environment.
Compensation is included for the effects of temperature,
discharge rate, charge rate and battery aging.

To provide precise measurements of current, voltage and
temperature, the PS810 integrates a highly accurate
15-bit + sign, sigma-delta A/D converter. Based upon
operating conditions, this programmable converter can be
configured to measure specific battery parameters with a
resolution of 8 to 15 bits + sign. Precision measurements
combined with advanced algorithms provide accurate
indications of capacity, run time, State-Of-Health and
safety and charge/discharge conditions.
The ability to operate directly from a single Li Ion or Li
Polymer cell minimizes the need for external compo-
nents, such as a voltage regulator and voltage divider.
To further limit external circuitry and enhance accuracy,
the PS810 provides an integrated temperature sensor
and oscillator.
