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.
Supporting both I2C and SMBus interfaces, the bq25703Aand bq25700A feature a 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.
The device's USB Power Delivery compatibility offers an input voltage range from 3.5 V to 24 V, which designers can use in multiple ports including USB 2.0, USB 3.0 and the newest standard, USB Type-C.
And the new charge controllers support input-ready devices from 5 V to 20 V and adjustable output for USB OTG with programmable current regulation.
The new battery-charging algorithm and intelligent detection features enable the battery charge controllers to support wide input and output voltage ranges and more compact adaptor designs.
The devices support 1S to 4S batteries and an efficient transition between buck and boost operation without any dead zone.
