Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hi Jesus,
Thanks for your patience. It is recommended to turn on the port after detection + classification if you do not an immediate action. This is a safer way than direct turn-on. Meanwhile, most of PD has PSE-PD handshake indication functions (for…
Hi Yao,
In a 802.3BT compliant PSE auto mode, the power cut threshold is 90W for Class-8 PD. If the PSE continuous output power is higher 90W it may turn off the port. A transient power could be 99.9W but not continuous.
Best regards,
Diang
Part Number: TPS23881 Tool/software: We plan to use TPS23881 Type-4 4 Pair 8 Channel PSE controller for our new project. What is the maximum number of RJ45 connectors that can be connected to a single chip? We have a requirement of 8x 10G RJ45 ports…
Part Number: TPS23881 Tool/software: Dear TI experts,
Now my customer proceeds CE certification with their product using TPS23881.
One of the test they have to control output current limit.
In the datasheet, output contol limit is controlled automatically…
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: Dear team,
I have a question. There is no over-voltage protection description on TPS23881 datasheet.
Power is also removed when the port voltage is higher than the over-voltage protection threshold, which is typically…
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: TPS23881 Tool/software: Hello, I believe I have managed to setup TPS23881 into (manual) mode that seem to be compatible with MAX5982A EVKIT ( which is in pre.bt class5 mode).
Below is a dump from serial terminal (pre.bt class -eval card on…
Part Number: TPS23881 Other Parts Discussed in Thread: TPS2384 Tool/software: Hi TI team
Our project use the TPS23881 as PSE controller. For the FUSE, We find two similar case about usage of TPS2384 but we still has some question as below:
1. I saw tha…
Part Number: TPS23881 Other Parts Discussed in Thread: TIDA-050026-23881 , MSP430F5234 Tool/software: How are dual simultaneous power supplies attached to the TPS23881 controller for doubling the available power?
