Dallas Fuel Gauge IC calculate the remaining capacity of lithium batteries, direct power supply

In Electronic Infomation Category: R | on December   1, 2010

Dallas Semiconductor (Dallas Semiconductor) has introduced a fuel gauge can be used independently of the IC DS2781. The chip directly from 2.5V to 10V power supply, calculate the 1 or 2 lithium and IRFBC40 datasheet and lithium-polymer battery remaining capacity.
DS2781 provides 16-bit current test, 11-bit voltage and IRFBC40 price and temperature testing, on-chip nonvolatile memory to record the characteristics of the battery data and IRFBC40 suppliers and application performance parameters, the IC can use the stored data to calculate the remaining battery power. In addition, their on-chip algorithms and status reporting capabilities reduce the interaction between the chip and the host, while software development is also very simple.
DS2781 by calculating the resistance of a low-resistance voltage drop sensor to achieve the current test, the sensor resistance can be programmed to compensate for the errors caused by temperature, so you can use low-cost high precision sensor resistance testing. To further improve the current test accuracy, DS2781 also provides automatic current-offset correction and user-programmable enhanced compensation.
DS2781 Fuel Gauge 8-pin TSSOP lead-free packaging, order quantities over 1,000 pieces priced at $ 2.90 (for reference).
