Our broad portfolio of battery charger ICs provide safe charging for 1- to 3-cell Li-Ion (Li+)/Li-Polymer, LiFeP04 NiMH/NiCd, lead-acid and rechargeable batteries of other chemistries in various sizes.

  • High-efficiency switching battery chargers provide fast-charging solutions up to 9A for high-capacity batteries.
  • Battery charger ICs with integrated fuel gauge offer small solution size and simplify the system software design.
  • AccuCharge technology leverages the integrated fuel gauge to improve the charging accuracy that is critical for small battery applications as well as fast-charging applications. These ICs also makes charge management simpler and enables fast-charging for parallel batteries of different capacities spaced far apart.
  • USB Type-C chargers with integrated CC detection and BC1.2 detection offer a single-chip solution for USB Type-C and legacy USB systems.
  • USB-Type-C Power Delivery chargers operate across the 5V to 20V supporting the full range of USB-C Power Delivery while maintaining backward compatibility to legacy USB systems in a compact solution size .

Our battery chargers are suitable for use in popular applications such as AR/VR devices, DSLR cameras, mobile point-of-sale (mPOS) devices, wearables, Bluetooth® headsets, IoT devices, portable medical devices, mobile phones, tablets, industrial computers, and 2-in-1 computers.
