TI has finally released a new Battery Booster pack for their Launchpad Range so let's have a quick look at it.
I reviewed the original one a couple of years ago (2014) see here:- element14.com/community/roadTestReviews/1712 and element14.com/community/videos/11461/l/reparing-a-suicidal-boost-regulator-on-the-fuel-tank-ti-booster-pack-pt1-removal and even though it had a few design flaws, I was disapointed to see it discontinued
Now it is time to look at the replacement, the charger and gas guage are updated, the sketch / demo software works first time and there are a few improvements, some of which I mentioned on the original review.
It still defaults to the power hungry but more stable output voltage mode of operation for the onboard buck/boost regulators but that's easy to correct and at least it is now mentioned in the user guide.
The difference is between running for just a few days or several weeks. depending on the target use, it may be worth making the change (Simply move two surface mount resistors).
Here is the new reference for the battery booster pack

The USB LIPO charger chip

and the gas Gauge chip

The buck/boost data sheet covers both models ti.com/lit/ds/symlink/tps63001.pdf, these timy chips can handle 800mA output each, thats pretty good
