The DS2740U+TR from Analog Devices (Maxim Integrated) is a high-precision Coulomb counter that provides critical current measurement data for battery capacity monitoring in cost-sensitive applications. This device offers 15-bit bidirectional current measurement capabilities, with a dynamic range of ±51.2mV and options for ±2.56A or ±5.12A with external sense resistors.
The DS2740U+TR utilizes a Dallas 1-Wire interface, allowing host systems read/write access to status and measurement registers. Each unit possesses a unique 64-bit device address, facilitating individual addressing in multibattery slot operations. The interface supports standard and overdrive timings.
With a current accumulation register resolution of 6.25μVhr, and options for 0.3125mAhr or 0.6250mAhr with external sense resistors, this IC is well-suited for detailed battery state tracking. It operates with a supply voltage range of 2.7V to 5.5V, featuring low power consumption with an active current of 65μA max and a sleep current of 1μA max.
Packaged in an 8-pin μMAX, the DS2740U+TR is available in tape-and-reel format, making it suitable for automated assembly processes. Its analog input filter extends the dynamic range for pulse-load applications.
