For the PVDD_B、PVDD_C, PVDD_D is 12V,but PVDD_A is 5V,GVDD_X and VDD are 12V, will this a problem? For the PVDD A,B,C,D is not the same voltage. and also how about the PVDD_A is 0V, but others PVDD are still 12V? thanks

Hi Rick
Thanks for your help,
The application is drive the relay and proportional electromagnetic.
M3,M2,M1 is all zero.
For 12V output to drive the proportional electromagnetic, frequency is 10K.
For 5V output, it is DC to drive the relay.
So will this be a problem? thanks.

Hi Duncan
Thanks for the feedback, and one more confuse for the PVDD_A leakage. when only apply the GVDD_X and VDD with 12V, the PVDD do not have power supply
we have find a leakage on PVDD from other supply. the PVDD have a 5.4V leakage voltage and using 1k resistor can only pull this pin to 1.2V. so could you kindly suggest where is the leakage from GVDD_X and VDD to PVDD? thanks for your support.
B.R.
