Hello,
Yes, this is an NXP part, but since this is a customer special part due to contractual reasons, I am not allowed to provide any information about customer-specific parts.
Customer specific device was made by NXP based on a specific contract for the specific company, only they can obtain the information, all information is confidential.
I cannot give you a recommendation because I don't know the design of the charger, the only thing I can recommend you is to contact whoever designed the charger so they can give you some recommendations.
Hope this helps.
Regards.
