PRODUCT OVERVIEW

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.

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
