TPS26630-33EVM: Connect TPS26630's FLT and PG for complete PGOOD function

Part Number: TPS26630-33EVM

Hi Team:

I want to use one pin to indicate OCP, OVP, UVP, OTP and power good, so should I connect PG and FLT together to achieve this function?
Or use a diode between PGTH and FLT like in the picture I pasted? THANK YOU.

In addition, I need to combine two parallel tps26630's Imon signals into a single IMON pin to FPGA, how can I calculate the appropriate Rimon? The maximum current of the system is 5A

THANK YOU.

    Hi Chen,

    You should not short PG and FLT because one is active low and other is active high. 

    You will need to connect FLT pin like PG by using a separate resistor from a supply. 

    For IMON calculation refer datasheet.
