BQ25040DQCR Description

Short technical summary and product information.

The BQ25040DQCR from Texas Instruments is an integrated linear battery charger IC specifically designed for space-constrained portable devices. It supports charging a single-cell Li-ion battery with a maximum charge current of 1.1A.

 

This device operates from an input voltage range of 4.35V to 6.7V, with an absolute maximum input voltage rating of 30V, offering robust protection against overvoltage conditions. It features a 1% charge voltage regulation accuracy and a 10% charge current accuracy. Additionally, it includes a 50mA integrated low dropout linear regulator (LDO).

 

The BQ25040DQCR supports standalone control interface and operates within a temperature range of -40°C to 125°C. It is available in a compact 10-WSON (3x2 mm) package, making it suitable for applications where space is a critical factor.

 

Key features include input overvoltage protection (OVP), input voltage dynamic power management (VINDPM), thermal regulation, and thermal shutdown protection. It also incorporates a soft-start feature to minimize inrush current and provides status indication for power good and charging/done.
