Other Parts Discussed in Thread: TPS2663, LM74502-Q1
hi Sir
I want to add a new function, to detect the status which is forward direction or reverse block
did you have any extra circuit to arrive the function, or other parts propose?
thanks

Hi Chen,
LM5050-1 allows only forward current flow. It does not allow flow of current in reverse direction.
If you can measure the Gate-Source voltage, you will be able to detect if there is forward current flow. When there is flow of current in forward direction, the Gate-Source is high. If there is reverse current flow, the Gate-Source is low (Shorted with input).
May I know what is the input voltage and load current range in your application.
Please have a look at TPS2663. This device can be operated up to 60V and 6A. The FLT/ pin of this IC is asserted low when a reverse current is detected.
Hi Chen,
We do not have this feature integrated in our Ideal diode controller devices which can support> 50A load current (Controller + External FETs).
This feature can be implemented using a sense resistor + comparator based based discrete circuit. To allow bidirectional current flow, you will need to use LM74502-Q1 controller.
Can you give us more information on the End Application and why reverse current flow detection is required ?
