Part Number: BQ51013C

Tool/software:

Hello,

I am an FAE at a distributor that handles TI products.
My customer is considering the BQ51013C and gave me some questions.

(Question 1)
Does my customer need to register as a WPC member if they use this product?
(Question 2)
Is there any information on Pin FMA?
Operation check results for opening each pin and shorting adjacent pins
(Question 3)
Are there any restrictions on the GND pattern regarding the layout?
How to separate analog GND and digital GND, etc.
(Question 4)
Are there any time restrictions when the EN signal changes from "H" to "L"?
Please let me know if there are any other points to be aware of regarding EN control.
(Question 5)
What points should I take into consideration when designing the structure around the receiver coil?

Best regards,

    What would be your concerns with H to L transition?

    The receiver coil area will be exposed to AC field from the TX, this will heat metal in this area the most and also most contribution to FOD issues.  This such as screws, battery and PCB should be kept to minimum or shielded.
