The TPS65800 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 8x8-mm package. The high level of integration enables typical board area space savings of 70% when compared to equivalent discrete solutions, while implementing a high-performance and flexible solution, portable across multiple platforms. If required, an external host may control the TPS65800 via I²C interface, with access to all integrated systems. The I²C enables setting output voltages, current thresholds, and operation modes. Internal registers have a complete set of status information, enabling easy diagnostics, and host-controlled handling of fault conditions.
