Part Number: TPS23881 Tool/software: I am designing a circuit using the TPS23881 with the following configuration:
2 ports with 4 pairs(4X4)
We need a forced power supply method. We set the POE mode to manual mode and do not enable detection and classification…
Part Number: TPS23881 Tool/software: Hi TI Team，
Hello, we want to use the 23881 for POE port control. In Germany, they want to achieve the on and off of any POE using physical switches. I saw that the 56th pin OSS can switch on and off the POE control…
Part Number: TPS23881 Other Parts Discussed in Thread: TPS23882 Tool/software: Hi TI Team,
The customer uses TPS23881, and they want to make 8 POE ports and 2 data ports, so the number of channels of TPS23881 is not enough, so if two 23881 ports are…
Part Number: TPS23881 Tool/software: Hi,
We are using the TPS23881 device in our design, configured in Configuration-A mode, where it operates in 8-bit access mode. In this mode, the 8-channel PSE device is logically split into two 4-channel devices…
Part Number: TPS23881 Other Parts Discussed in Thread: TPS2373 Tool/software: Good day, community,
I have successfully connected a device using the demo code in automatic mode, configured for 4-pair operation. As shown in the image, both ports used…
Part Number: TPS23881 Tool/software: TPS23881 can expand the maximum power sourced from 90 W to upwards of 125 W,
What is the output power range of the PSE and pd terminals for POE power supply, and does the output power of the pse terminal be greater…
Part Number: TPS23881 Other Parts Discussed in Thread: MSP430F5234 Tool/software: Hi TI team
We would like to to confirm if we can remove the 32.768KHz crystal of MSP430F5234+TPS23881 PSE solution. We test the 32.768KHz crystal but it can't output any…
Part Number: TPS23881 Tool/software: I am using TPS23881 PSE controller device in my design. Do we need to configure the TPS23881 on every booting time or it is required only one time configuration. Kindly clarify.
Part Number: TPS23881 Tool/software: I need to determine if the SRAM on TPS23881 needs to be loaded every time the microcontroller starts or if it can be initialized just once.
Part Number: TPS23881B Tool/software: Hi Dear experts,
I want to use TPS23881B in autonomus mode. I have a question to be sure.
Do I need any micro controller to upload a code to use it in autonomus mode? Or should I just connect AUTO pin (52) to…
