BQ25050DQCR Description

Short technical summary and product information.

The BQ25050DQCR from Texas Instruments is a compact Li-Ion linear battery charger designed for space-limited portable applications. It efficiently charges single-cell Li-Ion batteries at up to 1A charge current, operating from USB ports or AC adapters.

 

Key electrical specifications include a 30V input voltage rating with 10.5V over-voltage protection, ensuring compatibility with unregulated adapters. The device offers precise battery voltage regulation accuracy of 0.5% and charge current regulation accuracy of 7%. It also integrates a 50mA low dropout linear regulator (LDO) for system load.

 

This charger IC is housed in a small 10-WSON (3x2mm) package, suitable for surface mounting. It operates within a temperature range of -40°C to 85°C and supports battery NTC monitoring during charge and discharge cycles. Status indications for charging, done, and temperature faults are provided.

 

Applications for the BQ25050DQCR include smartphones, mobile phones, portable media players, and other low-power handheld devices where space and power efficiency are critical.
