A pair of highly flexible, single-chip buck-boost battery charge controllers for one- to four-cell (1S to 4S) designs has been introduced by Texas Instruments (TI). 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 bq25703A and bq25700A feature a new advanced battery algorithm enabling full power output by adding intelligence to battery charging through maximum power point tracking technology. The algorithm, referred to as input current optimisation (ICO), automatically detects the full capacity of input power to optimise current, while maintaining consistent system and charging current to ensure the utilisation of maximum input power.
The bq25703A and bq25700A expand TI’s portfolio of battery-charger solutions, offering switch-mode fast chargers and linear chargers for a broad variety of applications and power levels.
