PS810 Data Sheet Li Ion Single Cell Fuel Gauge
The PS810 is a fuel gauge for one-cell Li Ion or Li Polymer
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 microcontroller.
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 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 components,
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.
