Battery Fuel Gauge Chip
This feature however is disabled by firmware since the demo kit is shipped to customer with non rechargeable 1 5v aaa battery.
Battery fuel gauge chip. Users of pro charging systems battery gauges say these are the most advanced accurate and reliable battery fuel gauge on the market today. Battery management ics 475 battery authentication ics 5 battery charger ics 273 battery fuel gauges 115 battery monitors balancers 26 battery protectors 56 dc dc switching regulators 1585 buck boost inverting regulators 69 buck boost inverting controllers external switch 14 buck boost inverting modules integrated. 1 4 series li ion battery pack manager battery fuel gas gauge download datasheet. The ltc2942 measures battery charge state battery voltage and chip temperature in handheld pc and portable product applications.
The output current can is programmable to be between 130 ma and 1100 ma. Its operating range is perfectly suited for single cell li ion batteries. The rt9428 is a compact host side fuel gauge ic for lithium ion li battery powered systems. Impedance track technology based fuel gauging.
The gauges can also be configured to work with lithium ion batteries using a. Pro charging systems battery gauges are designed for use with 12v 72v lead acid wet cell and agm batteries. The ds2782 remains in production however for new projects we recommend modelgauge m5 max17201 fuel gauge. The ds2782 measures voltage temperature and current and estimates available capacity for rechargeable lithium ion and lithium ion polymer ba.
For the embedded fuel gauge function the state of charge soc calculation is based on the battery voltage and the dynamic difference between battery voltage and relaxed ocv to estimate the increasing or decreasing soc. A battery fuel gauge ic can predict how much longer under specific operating conditions the battery can continue to provide power. The mcp73113 is a single cell highly integrated li ion battery charge management controller for use in space limited and cost sensitive applications. If you are interested to learn more about this technology check this white paper.
On chip temperature measurements eliminate the need for a thermistor in the battery pack. A battery fuel gauge also known as a battery gas gauge determines battery state of charge soc and state of health. Patented gauging impedance track technology allows higher accuracy. The mcp73113 can accept an absolute maximum of 18v input and provides a 6 5v overvoltage protection.
Using a built in coulomb counter these fuel gauge ics calculate battery charge and store the data in 16 bit resolution for retrieval by the system controller access is via an industry standard i c interface enabling the. St s battery fuel gauge ics can be located in the battery pack or in the handheld device and integrate functions to monitor the battery voltage current and temperature.
