The DS2740U+T&R is a high-precision Coulomb counter designed for battery-capacity monitoring in cost-sensitive applications. It provides 15-bit bidirectional current measurement with a dynamic range of ±51.2mV. The device features a Dallas 1-Wire interface for host system communication and a unique 64-bit device address for individual addressing.
Key electrical specifications include a low active current of 65μA max and a sleep current of 1μA max. The operating voltage range is from 2.7V to 5.5V, with an operating temperature range of -40°C to 85°C. The DS2740U+T&R is supplied in an 8-pin uMAX/uSOP package suitable for surface mounting.
This IC is primarily intended for location on the host system but is also suited for mounting directly in the battery pack. Its current accumulation register resolution supports various external sense resistor values, enabling flexible application design.
