DC1812A-B - LTC2944 Demo Board | 60V Battery Gas Gauge (req. DC2026)

Demonstration circuit 1812A-B features the LTC2944. Demonstration circuit 1812A-C features the LTC2943-1. The LTC2943/LTC2943-1 has an operating range of 3.6V to 20V, while the LTC2944 has an operating range of 3.6V to 60V, making all three devices perfectly suited for multicel 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 LTC2943/LTC2943-1 measures voltage, current and temperature with an internal 14-bit No Latency ∆∑™ ADC. The LTC2944 measures voltage, current and temperature with an internal 16-bit No Latency ∆∑ADC. The measurements are stored in internal registers accessible via the onboard SMBus/I2C interface.
