TI's three-in-one switching boost converter achieves lowest quiescent current for small medical and personal electronics applications
Texas Instruments (TI) introduced a new switching battery charger integrated circuit (IC) that supports a termination current of 20 mA. Compared to competing devices, which typically support a termination current higher than 60 mA, TI’s BQ25619 enables 7% higher battery capacity and longer run time. The BQ25619 charger also delivers three-in-one boost converter integration and ultra-fast charging, offering 95% efficiency at a 4.6-V and 0.5-A output. Additionally, with the industry’s lowest quiescent current, the new charger can double the shelf life of ready-to-use electronics.
The BQ25619 charger helps engineers design more efficiently for small medical and personal electronics applications such as hearing aids, earbuds and wireless charging cases, IP network cameras, patient monitoring devices and personal care applications.
The BQ25619 expands TI’s portfolio of industry-leading battery-charger solutions, offering single- and multicell switch-mode chargers for high-capacity batteries, as well as linear chargers with high integration to extend battery run time and reduce total solution size.
Designers can use the BQ25619 evaluation module (EVM) to easily evaluate the device’s features and performance and speed time to market.
The BQ25619EVM is available for US$99.

The BQ25619 is available now through the TI store and authorized distributors. Offered in a 24-pin wafer quad flatpack no-lead (WQFN) package, the charger is priced at US$1.45 in 1,000-unit quantities. The 30-pin BQ25618, with similar features, will be offered in a smaller wafer chip-scale package (WCSP) in the third quarter of 2019.
