I am starting with the design of a power backup system for a project. I have a 7.2 V / 12.8 Ah Lithium Ion battery connected…
On the failed ICs pins do you see any difference when you measure with an ohm meter?
Just to confirm your design is a BQ2057W, Dual Cell not BQ2057C single cell?
The BQ2057C is mentioned in the post title?
Can you send layout plots for review?
Part Number: BQ2057C Other Parts Discussed in Thread: BQ2057 , I am using the BQ2057 to charge a 10Ah battery at 225mA charge current. The MOSFET is not getting too hot, but the BQ2057C is getting to 60C. Since I'm trying to pass this product through UL985…
Part Number: BQ2057C Hi team,
Here's an issue from the customer may need your help:
The customer would like to know the approximate power consumption of this BQ2057C associated circuit when the battery is powered after the lithium battery is charged…
Hi Nick,
Sorry for the misleading description, indeed they are asking regarding the BQ2057C, w hat is the difference between the common thermistor and the 103AT used by the BQ2057C?
Thanks and Best Regards,
