Part Number: BQ51050B
Hi,
I am trying to debug a problem with our product. It is a small wearable device that has a 40mAh LiPo battery for the power source.
We are using wireless charging to recharge the battery as the unit is sealed.
We are using the BQ51050B chip to control charging.
Our Rlim is 6.39k (Rfod = 200R and R1 = 6.19k). This gives us approx. 43mA charge current.
I have noticed that the datasheet says that the BQ51050B has a minimum charge rate of 500mA.
Will the device perform correctly when configure to charge at 43mA??
The problem I am experiencing is that some LiPo batteries used in our product do not charge correctly. In fact the communication with TX system is fine, but when battery is connected to BAT (pin4 BQ51050), the voltage pulses between @2.4V and @3.0V DC...
Thanks
