The BQ2014SN-D120G4 is a Texas Instruments single-cell lithium-ion battery charger IC optimized for space-constrained applications. It operates with a wide input voltage range of 2.7V to 5.5V, making it suitable for USB and wall-adapter powered systems. This specific variant, denoted by the “-D120G4” suffix, is packaged in a space-saving 6-pin WSON (WCSP) package, measuring 2mm x 2mm. The device features a selectable charging current up to 1000mA, configurable via external resistors, and incorporates several safety features including thermal shutdown and over-current protection. Its integrated power path management allows for system power to be sourced directly from the input while simultaneously charging the battery. The BQ2014SN-D120G4 utilizes a constant-current/constant-voltage (CC/CV) charging algorithm with an adjustable charge voltage. Its small size and high efficiency make it ideal for portable devices, wearables, and other applications where minimizing footprint and maximizing battery life are critical design considerations. The precise control over charging parameters simplifies design and ensures optimal battery performance and longevity.
