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


  • 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.
