LTC2943 Demo Board | 20VIN, 0.5A Battery Gas Gauge w/ Ext RSENSE (requires DC2026)
Analog Devices Inc.
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.
