DALLAS, July 18, 2017 /PRNewswire/ -- Texas Instruments
(TI) (NASDAQ: TXN) today 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. To learn more about the bq25703A and bq25700A, see www.ti.com/bq25703A-pr and www.ti.com/bq25700A-pr.
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.
Key features and benefits
- Input source flexibility: 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.
- Wide USB On-the-Go (OTG) output compatibility: The new charge controllers support input-ready devices from 5
V to 20 V and adjustable output for USB OTG with programmable current regulation.
- Compact configurations: TI's 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.
- Seamless transition between different modes : The devices support 1S to 4S batteries and an efficient transition
between buck and boost operation without any dead zone.
The bq25703A and bq25700A expand TI's portfolio of industry-leading battery-charger solutions, offering switch-mode fast
chargers and linear chargers for a broad variety of applications and power levels. Learn more about TI's battery charging solutions for accurate, dependable and faster, cooler charging and how TI's USB Type-C ecosystem provides protected power delivery for low power applications.
Tools and support
Designers can use the bq25700A evaluation module (EVM) to easily evaluate device features and performance and speed
time to market. The bq25703A EVM and the bq25700A EVM are available from the TI store and authorized distributors for US$149.00. Designers can use the WEBENCH® Battery Charger Designer to calculate the efficiency of the battery
charge controller.
Availability, packaging and pricing
The bq25703A and
bq25700A charge controllers are now available through the TI store and authorized distributors. Offered in a
4-mm-by-4-mm, 32-pin quad flat no-lead (QFN) package, the controllers are priced at US$2.20 in
1,000-unit quantities.
