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…
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 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…
Part Number: BQ2057C Hi
My customer use BQ2057C to charge battery. The current sense is 0.1 ohm, transistor is FZT788B, the actual charging current is only about 200mA in the case of 5V voltage, and can rise to more than 400 mA when it reaches above…
Part Number: BQ2057C Other Parts Discussed in Thread: BQ21040 Hi team,
Using the BQ2057CDGKR, set the 6.67 mA charge current, test the discharge time and find that the battery output is 0V, that is, disconnect the battery to disable the battery discharge…
Part Number: BQ2057C Other Parts Discussed in Thread: BQ2057 , BQ24040 Hi,
Kindly know how to calculate the RT1 & RT2 value of the NTC block resistor.
Battery: 3.7V/2200mAh
Battery has inbuilt thermistor resistor, value of 10K. Data sheet is attached…
