Flexible 4-A charger ICs offer universal input, ultra-fast charging in smartphones and tablets

Summit Microelectronics has introduced the industry’s first monolithic 4 A Li-Ion battery charger integrated circuits (ICs).

The SMB349 and SMB359 are fully configurable and can deliver up to 4 A charging/system current while accepting a wide +3.6 to +16 V input voltage range. The SMB349 incorporates CurrentPath technology with dual system/battery outputs (for instant-on with discharged or missing battery), while the SMB359 provides a single output.

Both products include Summits FlexCharge automatic power source detection and patented FlexCharge+ automatic input voltage detection technologies to support universal USB/AC battery charging and comply with industry standard like USB2.0/3.0/BC1.2. Also Summits patented TurboCharge high-efficiency switch-mode charger, TurboCharge+ automatic float voltage compensation and OptiCharge automatic input current limit technologies, combined with SafeCharge JEITA/IEEE1725 battery safety support, optimize the solution and provide the industrys fastest, safest battery charging.

Like all of Summits battery charging solutions, these devices are highly integrated and highly flexible. Digital I2C control and non-volatile configuration allow for host-based control while maintaining the simplicity of stand-alone operation. Parameters and functions are easily reconfigured for various applications or system modes. High integration keeps external components to a minimum while high-frequency operation and CSP packaging contribute to a tiny solution size.

The SMB349/359 are the ideal charging and system power solutions for virtually any portable application that utilize high-capacity batteries, require reliable and fast charging and feature very compact industrial designs. Target portable devices include smartphones, tablets, ultrabooks, digital camcorders, portable media players, and portable game consoles/controllers.
