Forum Post: RE: Standalone Liion charger
The bq24296 running in default mode might work for you. It has 12 hr safety timer.If not, the bq24170 or one of its siblings, with external resistors that set the timer and other parameters might work.

No. The PFET is controlled by the VBAT_UV circuit. If that is functioning correctly, the PFET should open.

Jason is quite probably correct. Out gauges can actually handle upwards of 10,000 I2C transactions per second, but if you hammer it continuously over I2C then the IC will not have time to reset the...

Those are all of the PbA batteries that have been characterized so far and I have not heard of an issue with ChemID's 800-802. You can collect log data and I will use our Mathcad program to try to find...
View ArticleForum Post: RE: bq24650 2S charging
Hello,The most likely reason for why the output voltage is 12.4V instead of 12.6 is a result of the voltage divider produced by R13 and R15 on the EVM. There resistors while they are precise still have...
