BQ25171QWDRCRQ1 Description

Short technical summary and product information.

The BQ25171QWDRCRQ1 from Texas Instruments is an automotive-qualified, standalone 800mA linear battery charger IC. It is designed to charge 1- to 2-cell Li-Ion, LiFePO4, and 1- to 6-cell NiMH batteries.

 

This device features a wide input voltage range of 3V to 18V, with an absolute maximum rating of 40V, making it suitable for automotive environments. The charge voltage is programmable from 3.5V to 8.4V for Li-Ion and supports 1- to 6-cell NiMH configurations. The charge current is programmable from 10mA to 800mA, with a high accuracy of ±0.5% for voltage and ±10% for current.

 

Key features include AEC-Q100 qualification, battery temperature monitoring via NTC thermistor input, IC thermal regulation, and input overvoltage protection. It also offers automatic sleep mode for low power consumption and integrated fault protection against overcurrent, over-temperature, overvoltage, and short circuits. The charger is available in a 10-VSON (3x3) package suitable for surface mounting.

 

The BQ25171QWDRCRQ1 is ideal for applications requiring reliable battery charging in automotive systems, such as backup battery charging directly from the main battery, thanks to its 40V load-dump tolerance.
