TPS65381A-Q1: About using semiconductor processes and latch-up test

Hi,

My customer is using TPS65381A-Q1.
He has same questions.
Could you answer me the following questions, plsease?

Q1: Which semiconductor processes does TPS65381A-Q1 use?
-> CMOS? or BiC?

Q2: If it is CMOS, Did TI confirm latch-up test?

Best regards,
