Single-Chip Buck-Boost Battery Charge Controllers

Single-Chip Buck-Boost Battery Charge Controllers

Texas Instruments introduced a pair of highly flexible, single-chip buck-boost battery charge controllers for one- to four-cell (1S to 4S) designs. The bq25703A and bq25700A synchronous charge controllers support efficient 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.

Supporting both I2C and SMBus interfaces, the bq25703Aand bq25700A feature a new advanced battery algorithm enabling full power output by adding intelligence to battery charging through maximum power point tracking technology. The unique algorithm, referred to as input current optimization (ICO), automatically detects the full capacity of input power to optimize current, while maintaining consistent system and charging current to ensure the utilization of maximum input power.
