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.
