BQ25071DQCR Description

Short technical summary and product information.

The BQ25071DQCR from Texas Instruments is a linear battery charger IC designed for single-cell LiFePO4 batteries. It is suitable for space-constrained portable applications, accepting power from USB or AC adapters.

 

This charger IC supports a maximum charge current of 1A and features a 30V input rating with 10.5V input overvoltage protection, making it compatible with low-cost unregulated adapters. The BQ25071DQCR also includes a 4.9V ±10% 50mA low-dropout linear regulator (LDO) for powering external circuitry.

 

Key features include IC thermal regulation, input overvoltage protection, and a soft-start function to minimize inrush current. The device utilizes a LiFePO4 charging algorithm that bypasses the typical constant voltage mode current taper, reducing charge times. It offers programmable charge current via ISET and EN terminals, with 7% charge current regulation accuracy. The charger also provides battery NTC monitoring and charging status indication.

 

The BQ25071DQCR is available in a 10-WSON package with surface mount mounting type. It operates within an ambient temperature range of -40°C to 85°C.
