New Texas Instruments chip cuts battery charging time in half

There are very few people who would pick battery charging technology as a conversation starter, but at the back of our minds we all know that it’s an Android user’s pet peeve.

Well the Texas Instrument engineers have been working hard to alleviate this problem, as they’ve come up with a new battery charging chip which, at the very least, will reduce the time you have to wait for your phone to re-charge after a hard day’s work.

The new bq2419x family of chips will improve charging times by up to 50%, thanks to some unique battery path impedance compensation and efficient 4.5A switch mode charging. The chip offers up to 92% efficiency at two amps and 90% efficiency when operating at four amps.

Ok I promise no more engineering lingo, what this essentially means is that smartphones and tablets using these new chips will be more energy efficient whilst charging. In practice this will decrease the time taken to charge your device, and will also help to keep everything that little bit cooler whilst plugged in.

As a bonus, Texas Instruments has also built the discharge chip to offer the industries lowest resistance, increasing the run-time of your battery. Whilst this isn’t likely to improve your battery life astronomically, – CPUs and screens are much bigger problems for batteries – every little bit of extra juice helps.

There are also some safe-charging management systems, integrated current sensing, and other design features which are a big deal for manufacturers, but we don’t need to worry about those.

Now we just need to find out which smartphone or tablet will be the first to make use of this zippy charging technology.
