BQ24050DSQT +BOM

1-cell, 1-A, Li-ion linear battery charger with automatic AC/USB detection

BQ24050DSQT General Description

Designed for space-limited portable applications, the BQ24050DSQT is a highly integrated Li-Ion and Li-Pol linear charger with a high-input voltage range and input overvoltage protection. It can operate from a USB port or AC adapter, making it versatile for various power sources. The charger has a single power output for charging the battery and allows for a system load to be placed in parallel with the battery without affecting the charging process during the 10-hour safety timer. The battery is charged in three phases - conditioning, constant current, and constant voltage - with internal temperature monitoring and charge current reduction as needed. The charger also includes high accuracy current and voltage regulation, charge status display, and programmable precharge and termination current thresholds, providing flexibility and precision in the charging process
