What is the function of C11 and R6 ? Does it reduce EMI ?
I had used the C11 and R6, but find the C11 would be smoking, then BQ24133's SW pins will be breakdown, I don't know…

My costoemr had a trouble of RF characteristic and try to enhance ther rf performance.
1. Can you provide the datasheet of L2/L3 common mode choke ? we can't find it thru web.
2. Can you provide maximum value of C11 & R6 …
I want to know is the VOUT voltage equal to the voltage of the lithium battery？ what does adjustable fully charged battery ？does it mean there is many different fully charged battery ，ex 4.2V /CELL ,2.1V/CELL ,right？
besides，in design PMP4397 ， there i…
Part Number: BQ24133 Other Parts Discussed in Thread: PMP4397 Hi,
We are using "BQ24133RGYR" as per PMP4397 Reference Design. However we need to give charger connection status to the circuit at LOAD. The issue we are facing is that there are 3 GNDs in…
What are the differences between the two radiated emissions test results you attached? One shows a large spike around 250MHz and the other shows a large spike around 900MHz.
What is the charging current setting? If it is above 2A, please add a schottky…
As the power dissipated by the resistor is proportional to the value of the capacitor in the whole charging process, P=C*V^2*f, with a high input voltage and capacitor value, the power dissipated by the resistor will be a large one. For example…
