Texas Instruments  TPS65811RTQR

The TPS65810 device provides an easy-to-use, fully-integrated solution for handheld devices, integrating charge management, multiple regulated power supplies, system management, and display functions in a small, thermally-enhanced 8-mm × 8-mm package. The high level of integration enables space savings of 70% of the typical board area when compared to equivalent discrete solutions, while implementing a high-performance and flexible solution that is portable across multiple platforms.

If required, an external host can control the TPS65810 device through I2C interface with access to all integrated systems. The I2C enables the setting of the output voltages, current thresholds, and operation modes. The internal registers have a complete set of status information, enabling easy diagnostics, and host-controlled handling of fault conditions. The TPS65810 device can operate in standalone mode, with no external host control, if the internal power-up defaults are compatible with the system requirements.
