Abstract

This application note presents a ship mode implementation that can fully connect or disconnect the battery from any TI battery charger and its system load. The operating principles of the circuit, discussion of key MOSFET selection criteria, and demonstration of how the design can be implemented with either internal, external or no battery FET architectures are discussed.
