TPS65810 集成单节锂离子电池和电源管理 IC
TPS65810 描述
The TPS65810 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 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 TPS65810 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.
