HI,

For oneof our project we are planning to use the i.MX8DulxPlus Part# MIMX8DX5CVLFZAC (Without DSP) will be using LPDDR4.

For which i have query regarding the selection of PMIC part# As per the processor we need industrial grade PMIC part compatible for i.MX8DualxPlus and as per the datasheet of PMIC 33PF8100 there are several parts as below:

1) MC34PF8100FJEP Industrial grade compatible with LPDDR4

2) MC33PF8100FJES Automotive grade compatible with LPDDR4

We should go with the part#1 in above list, is this correct as per latest OTP programming support on this PMIC?

Or we should go with the other latest OTP programming ID from FJ??

Require your input to quickly converge on this.
