The Texas Instruments BQ25170DSGR is an 800-mA linear battery charger IC suitable for 1-cell Li-ion, Li-Poly, and LiFePO4 battery chemistries. It supports a programmable charge current from 10 mA to 800 mA and a programmable battery charge voltage up to 4.4 V.
Key electrical features include a minimum input voltage of 3V and a maximum of 6.5V, with an absolute maximum input voltage tolerance of 30V. The device offers high accuracy for both charge voltage (±0.5%) and charge current (±10%). It incorporates features like precharge current at 20% of ISET and termination current at 10% of ISET.
Designed for robust operation, the BQ25170DSGR includes comprehensive fault protection, such as overcurrent, overtemperature, overvoltage, and short-circuit protection. It operates within a wide temperature range of -40°C to 125°C. The charger also features BAT temperature thermistor monitoring and IC thermal regulation for safe charging profiles.
Packaged in an 8-WSON (2x2) surface-mount package, this IC is ideal for applications requiring efficient and reliable battery charging. Its standalone control interface and external resistor programmability simplify integration into various designs.
