Description
Demonstration circuit 1812A (Figure 1) features the LTC2943. The LTC2943 has an operating range of 3.6V to 20V making it perfectly suited for multicell battery applications. A precision analog coulomb counter integrates current measured through a sense resistor between the battery’s positive terminal and the load or charger. The default value assembled on the DC1812A-A is 100mΩ for a maximum current measurement of 500mA. The LTC2943 measures voltage, current and temperature with an internal 14-bit No Latency ΔΣ™ ADC. The measurements are stored in internal registers accessible via the onboard SMBus/I2C interface.
