3 Li-Ion Applications

Li-Ion battery is used widely across all the market sectors from high power industrial applications, such as power tools, to low powered small solution size personal electronics applications, such as TWS (True wireless stereo) headsets.

The BQ25170 and BQ25175 are standalone linear chargers that are used for charging single cell Li-Ion battery with multiple different voltage settings via resistor the BQ25170 is available in QFN package which is used across industrial applications while the BQ25175 is available in WCSP package for space constrained applications.

Also available are the feature rich BQ25180 and the BQ25155 host-controlled chargers with integrated power path to prioritize powering system over charging the battery. The BQ25155 has integrated LDO as well as 16-bit ADC for battery monitoring. The BQ25180 can support peak discharge currents up to 2.5A for some of the industrial applications with motors as a load.
