TPS2377-1: PD device was not connecting with PSE device.

Vignesh M69

Part Number: TPS2377-1

Dear Sir,

I test the PoE PD circuit built by using TPS2377-1. but if I connect with PSE device, the power LED of the PSE device (PoE Injector) was blinking. I attach the Schematic circuit also.

Hi Vignesh,

By blinking do you mean it's turning on to 48V? Or the injector is not even passing detection? Can you add a load (at least 10mA) between VDD and RTN?

Thanks!
