Hi Brandon,
I appreciate your responses; they are extremely valuable. In the auto mode configuration of the TPS23881, can power supply readings be obtained for each port? Also, is it possible to deactivate a port in auto mode?
Regards,
Jesus
Part Number: TPS23881 Hi team,
Since the MCU currently does not leave I2C control for TPS23881, I would like to confirm with you the necessity of this pin. If you think it needs to be controlled, please provide detailed relevant I2C communication procedures…
Part Number: TPS23881EVM-008 Hi team,
I have a few layout-related questions that I would like to ask you.
As shown in the picture below, the red line is the cutting line on the primary side and the secondary side. Is it feasible if we design this line…
Part Number: TPS23881 Hi,
We have TPS23881 on our board abd its firmware load at i2c set this device in Auto mode.
if we set the 0x12 register to set in Manual/ diags mode, the 0x12 register become 0x00 which is off mode.
is there any set of steps /sequence…
Part Number: TPS23881 We found that TPS23881 has an issue that cannot power on for the first time. And we found TPS23881 kept repeating detection function while the issue occurred.
We also found that adjusting detection resistor can recreate this anomaly…
Hi Ayush,
Thanks for your patience as I have been out of office traveling.
Can you confirm the following:
What operating mode are you in (Register 0x12)?
What is your port power allocation (Register 0x29) prior to turning on the ports?
Please confirm…
Part Number: TPS23881 Hi expert,
May we know if you have experience on Sifos PDA600 PHY min Port test? My customer would like to know how to design the value, is it 50V? They are testing Sifos MPSViolation_4 and found out current is lower than 16mA. Other…

The attachment is designed based on the reference circuit (TPS23881EVM-008) provided by our company. If it needs to be modified, please provide suggestions…
Part Number: TPS23881 I have a basic board with a TPS23881 that works up to around 45W to a powered device. However it cannot supply 90W.
There is no MCU connected to the TPS23881, nor do I change it's SRAM on power on. It's a fresh, out the box…
