MaxCharge technology enables 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 device, 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.
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 MaxLife battery fuel gauge technology to ensure longer battery life and safer charging of portable electronics.
The I2C-controlled 1S, 5A fast charger is featured in a new TI Designs reference design, TIDA-00538, utilising 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.
The bq25892, which is offered in a 4x4mm, 24-pin quad QFN package, is available now, priced at $2.50 and sold in 1,000-unit quantities.
