The BQ25171-Q1 from Texas Instruments is a standalone, 800-mA linear battery charger designed for automotive applications. It is AEC-Q100 qualified and supports multiple battery chemistries, including 1- to 2-cell Li-Ion, Li-Polymer, and LiFePO4, as well as 1- to 6-cell NiMH batteries.
This charger operates with an input voltage range of 3 V to 18 V, with an absolute maximum rating of 40 V, and features 40-V load-dump tolerance. It offers precise control with external resistors to set battery regulation voltage from 3.5 V to 8.4 V and charge current from 10 mA to 800 mA. Key electrical specifications include ±0.5% charge voltage accuracy and ±10% charge current accuracy.
Designed for reliability, the BQ25171-Q1 includes integrated fault protection such as 18-V input overvoltage protection, 1000-mA overcurrent protection, and output short-circuit protection. It also features thermal regulation at 125°C and thermal shutdown at 150°C. The device operates within an extended temperature range of -40°C to 125°C and comes in a compact VSON (DRC) package suitable for surface mounting.
Additional features include battery temperature monitoring via an NTC thermistor input, automatic sleep mode for low power consumption, and status/fault indication outputs. Its standalone interface and RC-settability simplify integration into various automotive power management systems.
