Part Number:BQ24115
Fellow engineers,
I would first append to the following thread: https://e2e.ti.com/support/power_management/battery_management/f/179/t/518127 ut things get probably more organized if we move to a more "specific" question.
I need to start a charger design for 4 x NiMH, and was considering bq24115. It appears that NiMH ain't the cup of tea on most discussions here, so is this part a safe route to take for such chemistry? Our system does have a MCU available and attached to the charger, and we can implement some "failsafe" features to try and allow charging only under given conditions.
The charging voltage suggested by the original poster there seemed a bit low for 3 cells (4.4V / 3 = only 1.47v/cell, I would expect ~1.55 to be more like it, but since NiMH are not exactly constant voltage, I might be totally off here).
This product is not a battery charger, it is a system with "the bonus of allowing user to charge his batteries" - so we are targeting something simple, not consuming too much real state. I guess the question is whether bq24155 is a good option for 4xNiMH, or if not, are there suggestions for an alternative?
Thanks
Bruno
