MAX77301
JEITA-Compliant, Li+ Charger with Smart Power Selector, Automatic Detection, and USB Enumeration
General Description
Benefits and Features
The MAX77301 is a JEITA-compliant* lithium-ion linear battery charger that operates from a USB port, a dedicated charger, or universal adapter. The IC provides automatic adapter-type detection and enumeration with a USB host or hub. The IC integrates independent battery charge switch, current sense circuit, MOSFET pass elements, thermal regulation circuitry, and eliminates the external reverse-blocking Schottky diode to create the simplest and smallest USB-compliant charging solution.
The IC includes automated detection of charge adapter type, making it possible to distinguish USB 2.
