Hello Aldmour :  

Thanks for your reply. because We received the attached file name as "BQ797xx_VIF_COMM_AN" 

we tested the thigh/tlow/trise/tfall timing cannot meet the table 3-1 timing chart. it's seems the timing spec different with BQ79718 and BQ79600-Q1 definition. could you please help review the Lee attached slide different tone and should we still need following the table 3-1 spec for the Common mode voltage ? thank you

Dear Aldmour Sir,

1. The Excel attachment is the B1 EIV test report. Compared to the previous phase, Common mode voltage has been added. Please help review the test report again to see if it is okay. The voltage specification for Common mode voltage is ±25V. There are two questions to clarify: 1.1 Is the common mode voltage specification of ±25V suitable for both PBQ79718B1PAPTQ1 and BQ79600PWRQ ICs? 1.2 There are two different specifications for common mode voltage in the following figure. Could you please explain the difference between these two?
