Description
- DC1812A-A, Demonstration Circuit features the LTC2943. The LTC2943 has an operating range of 3.6V to 20V making it perfectly suited for multi-cell 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 100m-ohm for a maximum current measurement of 500mA. The LTC2943 measures voltage, current and temperature with an internal 14-bit No Latency ADC. The measurements are stored in internal registers accessible via the on-board SMBus/I2C interface
