BQ24041DSQR Description

Short technical summary and product information.

The BQ24041DSQR is a linear battery charger IC from Texas Instruments designed for single-cell Lithium-Ion and Lithium-Polymer batteries. It delivers up to 1A charge current and features a pin-selectable USB input current limit of 100 mA or 500 mA. The device operates from an input voltage range of 3.5V to 6.9V, with an absolute maximum input of 30V.

 

This charger integrates multiple protection features including input overvoltage protection (selectable thresholds of 6.6V or 7.1V), thermal regulation at 125°C, thermal shutdown at 150°C, and short-circuit protection. The charge voltage accuracy is ±1% and charge current accuracy is ±10%.

 

The BQ24041DSQR is offered in a 10-WSON (10-WFDFN Exposed Pad) surface mount package, suitable for space-constrained designs. It is specified for operation over a junction temperature range of 0°C to 125°C.
