Texas Instruments develops chipset enabling half the time needed to recharge battery

Texas Instruments develops chipset enabling half the time needed to recharge battery
The new line of chips, seven in all, supply power twice as fast as the current generation of chipsets thanks to a new “battery path impedance compensation system.” These new integrated circuits for single-cell lithium-ion batteries can be used in a wide array of devices.

The “BQ2419x” line can find use not only in smartphones and tablets, but also LTE routers, Wi-Fi speakers, even mobile medical equipment and other portable devices.

It seems like battery technology has not been keeping pace with the advances in mobile hardware and network technologies. However, it has not been standing still either. Lithium-ion batteries have been seeing incremental improvements in density. The sector has also been contending with safety factors as well while it improves the technology overall.

The new TI “fast-charge units” meet Energy Star and EU charging specifications and are designed to run cool while being up to 92% efficient. That is not too bad for a component measuring just 4mm x 4mm. With smartphone sales expected to grow by leaps and bounds for the foreseeable future, this new chip by Texas Instruments is timely.

good question. i remember they were at a recent convention with their OMAP5 platform showing off what it can do with the SGX Rogue but other than that i haven't heard too much from TI.

So if this chip is inclined 3000Mah battery will take half-an-hour to fully recharge, that also depends on the voltage to!

I wonder if this can be paired with the Snapdragon 800... Quick Charge v2 + this = fully charged in 30 minutes

if we can keep getting quicker charge times then battery capacity wouldn't even really matter so much. o:

Exactly, who needs larger capacities when you can get fully charged in a matter of minutes? Granted, we don't have chargers everywhere, so capacity still matters somewhat. I think 2,100-2,600 mAh is good enough to get through a day, and if not then you can get a quick 10 minute charge somewhere in the day and squeeze a few more hours out of it.

They better have this on my next phone when my Galaxy Note 2 dies or something. LOL

I thought the battery built to charge faster not chip. If the new chip can charge any mobile battery half of the time it is great.

This chip with fast large charging battery would be great combo!
