TPS2561: Using only one channel of this device

Nitish Gupta

Part Number: TPS2561

Hello,

One of my customer's is using TPS2561 in their design for USB current limiter switch. They are only using one channel, so are shorting INx & ENx pins. Also, OUT2 is being kept as TP for now. Could you confirm if this implementation will work?

Thanks,

Nitish

Hi Ziv,

Thanks for confirming that EN2 can be connected to GND. How about IN2 pin? Can this be left floating if not used? TP means test point and customer is meant to leave it floating. Please comment. Thanks!

Hi Nitish,

For input pin, it's suggested to connect to GND instead of floating.
