Integrated 5V Boost and Lithium Battery Charging Management IC for Portable Power Applications
The TP5400 is a compact battery management IC designed to handle both lithium battery charging and 5V boost output for portable electronic systems. It integrates a single-cell lithium-ion/lithium-polymer battery charger along with a step-up boost converter capable of delivering up to 1A output current. This dual-function design makes it highly suitable for applications such as power banks, portable charging devices, and battery-powered embedded systems. The ESOP-8 package provides efficient thermal performance and compact PCB integration for modern portable electronics.
The IC supports standard constant current/constant voltage (CC/CV) charging for lithium batteries and efficiently boosts battery voltage to a regulated 5V output for powering USB devices or other electronics. Integrated safety features such as overcharge protection, overcurrent protection, and thermal shutdown enhance system reliability and battery safety. With minimal external components required, the TP5400 simplifies the design of compact battery-powered systems that require both charging and voltage boosting functionality.
