STBC15LJTR by STMicroelectronics

The STBC15LJTR is a high-efficiency, single-cell, lithium-ion/polymer battery charger IC designed and manufactured by STMicroelectronics, a global semiconductor leader known for its cutting-edge technology and solutions. This compact and integrated circuit is specifically tailored to meet the needs of portable applications where space and power efficiency are critical.

At the heart of the STBC15LJTR lies its ability to provide a constant-current/constant-voltage charging profile, which is essential for maximizing the lifespan and performance of lithium-ion batteries. The device can operate with an input voltage range from 4.5V to 5.5V, making it versatile for various USB-powered applications or wall adapters.

The charger features programmable charge current up to 700mA, allowing designers to tailor the charging parameters to the specific needs of their application. This level of customization ensures that the battery is charged efficiently and safely, in accordance with its specifications. Additionally, the STBC15LJTR includes a charge termination function, which stops the charging process once the battery is fully charged, preventing overcharging and enhancing battery longevity.

Safety is a key concern when dealing with battery charging, and the STBC15LJTR addresses this with multiple protection features. It includes over-temperature protection, which shuts down the charging process if the IC's temperature exceeds a safe threshold. There is also a built-in under-voltage lockout (UVLO) that ensures the device operates only when the input voltage is within an acceptable range.

The STBC15LJTR comes in a small 2.0 x 2.1mm flip-chip package, which is ideal for space-constrained applications. Its small footprint and low external component count make it a perfect choice for portable devices such as wearables, medical devices, and wireless headsets.

Overall, the STBC15LJTR from STMicroelectronics is a reliable and efficient solution for charging single-cell lithium-ion batteries, offering designers a flexible and safe way to incorporate battery charging into their portable applications.
