Part Number: TPS2054 Hello,
Could you provide me with the expected EOL for TPS2054BD ICs.
We are planning on integrating these chips in our design and wanted to know if there is a possibility of running into end of life issues in the near feature.
Are these…
Hi Ivan,
So here's probably some better clues as to what is happening. Looking at your comment:
"(3) D+ pullup must not be activated (high: 3.3 V) while the device is detached from USB or power supply is not applied on VDD and VCCx.
VBUS of USB…
Please check TPS2044, TPS2048, TPS2054 and TPS2058.
For TI's policy, I will first click resolved button.
If you have any other concern, contact me any time.
If you think resolved, please help click 'Issue is solved button'.
Thanks.
Hi, Sai loo,
You are correct. All those below parts share same UL report and the test module is TPS2044B, so the protection current is 5A. What's your concern about it?
TPS2041, TPS2042, TPS2043, TPS2044, TPS2045, TPS2046,
TPS2047, TPS2048, TPS2051…
Bob,
According to a thermal camera, and my finger, the switches are quite cool (room temperature), so there is no temperature issue.
Vin is a clean 5V. The EN inputs are also clean 5V, since they are (at the moment, at least) pulled up to Vin and disconnected…
Other Parts Discussed in Thread: TPS2054 I make the HUB_board for USB 2.0
I used to TUSB4041IPAPQ1
but the board is not working
We need to schematic review!
please check it

There were 2 issues
1. We were testing for Full Speed USB, but the hardware was configured to use ULPI. So changing this resulted in getting the interrupts
2. We are using a TPS2044 QUAD POWER-DISTRIBUTION SWITCHES for the VBUS signal, but 2044 has…

When an output of the TPS2054B is disabled (ENx=L) what are the limitations on how that output pin may be driven by other devices? I want to provide power to a circuit in two ways:…
