Industry's first single-cell Li-ion 5-A battery-charger IC can achieve 80 percent capacity in 30 minutes
DALLAS (May 4, 2015) – Enabling faster and cooler charging, Texas Instruments (TI) (NASDAQ: TXN) today introduced the industry’s first fully integrated 5-A single-cell lithium-ion (Li-ion) battery-charger circuit with proprietary MaxCharge technology that reduces charge time up to 60 percent compared to existing battery chargers. The bq25892 switch-mode charger gives users a safer charging experience while still maximizing the benefits of a faster charge time, currently unseen in the industry. MaxCharge technology provides faster charge times and cooler charging to improve user experience and extend the overall life of electronics in many Li-ion applications, including smartphones, tablets, drones, power banks, and industrial and medical equipment.
The highly efficient charger, which charges at 3.5A with minimal 18˚C temperature rise, facilitates faster and cooler charging by combining narrow-voltage DC/DC power path management with TI’s MaxCharge technology to support input voltages up to 14V while providing charge current up to 5A.
Features and benefits:
This fast-charging battery charger is designed to work in single-cell portable devices with TI battery fuel gauges. For example, pair a TI MaxCharge technology device with TI MaxLifeTM battery fuel gauge technology to ensure longer battery life and safer charging of portable electronics.
Tools and support
The I2C-controlled 1S, 5-A fast charger is featured in a new TI Designs reference design, TIDA-00538, utilizing MaxCharge technology for high input voltage and adjustable USB OTG boost, which enables turn-key access to reduce battery-charging time and improve battery run time during the discharging phase.
Availability and pricing
The bq25892 charger is shipping in volume production and available through the TI Store and the company's authorized distribution network. The products come in a 4-mm by 4-mm, 24-pin quad flat no-lead (QFN) package. The bq25892, for smartphones and tablets, is priced at US $2.50 in 1,000-unit quantities. In addition, TI introduced its new bq25895, which supports power banks and is priced at US $2.00.
