Texas Instruments has introduced a pair of single-chip buck-boost battery charge controllers for one- to four-cell designs.

The bq25703A and bq25700A synchronous charge controllers support charging through USB Type-C and other USB ports in end equipment ranging from notebooks and tablets to power banks, drones and smart home applications.

The battery charge controllers enable full power output through a new algorithm that adds intelligence to the battery charging through maximum power point tracking technology, TI says. The algorithm automatically detects the full capacity of input power to optimize current, while maintaining consistent system and charging current to ensure the maximum input power.

Both devices are available now through the TI store and through distributors priced at $149.
