Li-Ion battery charger ICs

22 August 2012 Power Electronics / Power Management

Summit Microelectronics has introduced two monolithic Li-Ion battery charger 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 Summit’s FlexCharge automatic power source detection and patented FlexCharge+ automatic input voltage detection technologies to support universal USB/AC battery charging and comply with industry standards like USB2.0/3.0/BC1.2.

The devices also feature Summit’s 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.

Digital I²C control and non-volatile configuration allow for host-based control while maintaining the simplicity of standalone 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.
