Part Number: BQ24074 Hello,
Quick question on the charge profile
Whilst plotting the charging characteristics we noticed that the charge seams to turn on and off is this normal ?
Just trying to understand what and why
The voltage and temperatures are…

I've read the documentation available…
Part Number: BQ24074
1) The battery charges "successfully" as in, as measured by a DMM, the current into the battery is dropping below the termination current and the voltage is up ~4.2V. I started with a battery at 3.6V. 2) The CHG pin does…
