Part Number: TPS23753A We have an outsourced manufacturer designing a device that contains a PoE PD circuit. The problem is that this device does not power up when connected to a PoE switch. Here is the device schematic for your reference. The PoE circuit…
Part Number: TPS23753A Hello. This is Steve.
I am writing to inquire about an issue that occurred while designing a POE product, as shown in the attachment.
I would appreciate a detailed response. Request for Review of the TPS23753APWR Circuit Diagrampptx…
Part Number: TPS23753A Hi,
We are designing a circuit based on the TPS23753A and are using the TPS23753AEVM-004 schematic as a reference. However, the HA3801-BL transformer used in the reference design is currently unavailable in stock.
We are considering…
Part Number: TPS23753A Tool/software: We are using TPS23753APW PD controller in the circuit mentioned below. Board is heating up when the power is given through PoE and Voltage of PoE increases gradually. We have seen it goes up to13.2V while the circuit…
Part Number: TPS23753A Hi, Good day
Regarding the part number TPS23753A, I detected in the datasheet 4 different MPNs and I would like to know what's the difference between those MPNs.
1.- TPS23753APWR
2.- TPS23753APWR. A
3.- TPS23753APWR G4 …

I designed a PoE powered device using TPS23753APWR , based on the PMP7355 reference design . The main difference is that I use a different transformer…
Part Number: TPS23753A Tool/software: Hi TI,
Good day.
Has TPS23753A with an over-current protection? If yes, may I know what the trigger conditions are?
I can't find the exact trigger conditions from its datasheet,
Sincerely
Webber
