Tool/software:
looking for some help in part selections.
I was hoping to find a suitable IC that offers the following characteristics and features.
USB input
suitable for charging a single 4.2v battery
i2c capable
1A peak charging
temp control isn’t a concern
low iq- but doesn’t really matter as it should only be active with vIN.
**monitoring charging voltage and charge current.**
ideally more than 6v input support
if it has an inbuilt buck converter, ideally more than 800ma
I didn’t read the datasheet close enough and selected a BQ25180, which doesn’t actually measure the charging current or voltage, and would prefer to use a single IC that does this rather than trying to integrate an extra component like a INA219 or similar. The 25180 from what I can tell only shows what is configured. Though it does show alerts for over charge, which is odd as I would think that implies it can detect voltage??
don’t get me wrong the 25180 does what it specifies, however I was hoping to the charge data out of it via i2c.
I’m using a MAX17048 for the gauge but haven’t been happy with that functionality either.
package format isn’t really a concern however something that would work on a two layer board would be preferable.
is there such an IC from TI that can accomplish the above - help!
