IC enables battery 'fuel gauges'

11 November 2009 Electronics Technology

STMicroelectronics introduced a battery condition monitoring IC enabling increased accuracy for ‘fuel gauge’ style indicators showing the operating time remaining.

The STC3100 can be located in the battery pack or in the target device, and integrates functions to monitor the battery voltage, current and temperature. It has a built-in Coulomb counter to calculate battery charge, and stores the data at 16-bit resolution for retrieval by the system controller. Access is via an industry-standard I²C interface, enabling the controller to create an accurate graphical representation of remaining battery operating time.

The device supports extra functionality by providing one external pin for use as a detector input or to drive an LED indicator. Each IC is also pre-programmed with a unique 64-bit identifier, which enables traceability of individual battery packs or subsystems. In addition, 32 Bytes of accessible RAM allow storage of battery history or application-related information throughout the lifetime of the battery.
