MAX77301

EVALUATION KIT AVAILABLE 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 2.0 device, USB charger, dedicated charger devices as well as standard input adapters. See Table 2. When enumeration is enabled, the IC automatically negotiates with a USB host, making it possible to achieve the highest-charging curren...
