Hey guys,
I'm working on a BQ24232 project, charging a 35mAh Lithium polymer unit.
I'm facing the following problem:
Whenever I attach power to charge the unit, the batteryvoltage increases really fast to 4,2V (within minutes).
The charging current then is decreasing until ITerm is reached.
I fear, the charging process isn't optimally configured for that tiny capacity. Could you give me any advice for optimization.
I've following config:
ILIM floating
ITERM floating
33k @ ISET for ~25mA charging current
TMR left floating
What I'm thinking about is a tiny R @ ITERM (~10-15 Ohms) to shift down I Term.
But, this isn't perfect solution in my opinon, because this just leads to a little more transfered energy.
Any other thing i could do to increase transfered energy amount?
Thanks for your help.
Best wishes,
Florian
