Programmable USB/AC Li-Ion Charger
Summit Microelectronics introduces its SMB138 programmable li-ion charger that is targeted at portable consumer electronics applications. Designed to optimize battery charging from any power source, including the Universal Serial Bus and other current-limited sources, it is suitable for the latest mobile devices. The charger delivers value at system level by reducing charge time and power dissipation. Its built-in flexibility to adjust to any input power source (100 mA/500 mA USB or 900 mA AC/DC) allows the use of a low-profile, single mini/micro USB data/power connector. Another feature is USB On-the-Go support that enables one USB device to supply power to and communicate with another USB device directly without the presence of a PC.
