BQ25070DQCR Description

Short technical summary and product information.

The Texas Instruments BQ25070DQCR is a compact, highly integrated linear battery charger designed for single-cell LiFePO4 batteries in space-limited portable applications. It operates from USB or AC adapter inputs, offering a wide 30V input voltage range with over-voltage protection.

This charger IC provides up to 1A of programmable charge current via a single CTRL input, ensuring efficient charging. A key feature is the integrated 4.9V ±10% 50mA low dropout linear regulator (LDO), which supplies power to external circuitry. The device employs a LiFePO4 charging algorithm, omitting the constant voltage mode typical in Li-Ion chargers.

Key specifications include a 7% charge current regulation accuracy, thermal regulation and protection, and a soft-start feature to manage inrush current. It also supports battery NTC monitoring and provides charging status indication. The BQ25070DQCR is available in a small 10-pin WSON package, suitable for surface mounting.

Applications for the BQ25070DQCR include smartphones, portable media players, and other low-power handheld devices where efficient battery management in a small form factor is critical.
