Part Number:BQ35100
Hello everyone,
I have a small microcontroller project with a single non-rechargeable (CR2430, 3V, Lithium Manganese Dioxide, 300 mAh) cell, followed by a boost converter for 3.3V output.
Don't know if it's relevant, so.. in sleep mode it draws some <0.1mA, while active mode consumption is >30mA.
I'm looking to add a battery gauge to my project, so that device could send current battery % value to operator, so that he can decide if it's time to replace the cell.
In TI battery management range I've only found BQ35100, that seems to suit my needs. But it's a rather large chip with 15 external components (in example circuit). Are there any alternatives I may have missed?
Is it possible to use BQ35100 to measure current consumption of my board in different modes of operation during debug?
Thank you!
