TPS65916: TPS659162 OR TPS65930400 to control the power sequence

Part Number: TPS65916

Tool/software:

Hello,

I am going to use the PMIC IC either TPS659162 OR TPS65930400 in my current design.

Please find the attached Image and below STEPS for the better understanding of the trquirment,

STEP 1 : Power will be given form the USB, 5V

STEP 2 : 5V is given to the TPS659162 /TPS65930400 and FX3 simaltaneously

STEP 3 : PMIC will make the GPIO High and it is given to the Switcher to generate the FX3 supply and then FX3 will ON.

STEP 4 : FX3 will enable the PMIC IC's supply sequence as per our requirement.

As I have read the datasheet and it mentioned that there is internal NVM which will pre programmed and control the power sequence and GPIO as a default functions but my requirement is slight different : at power ON, PMIC will ON and make one of the GPIO high to ON the power of the FX3 and FX3 will ON then FX3 will control the PMIC power sequence through I2C/SPI.

Kindly provide your suggestion, how can I achieve the requirement with the TPS659162 OR TPS65930400. 

Regards,

Alpesh
