Hi BP101,
You are not alone. When I read the schematic I also had the same doubt at first. The TARGET_VBUS which is connected to PB1 came from the TPS2052B power switches. The TPS2052B takes its power source from one of the three power sources (BoosterPack…
Hi,
In order to more clear to find out every reason, I suggest you to divid the TPS2052 form you system and use a separate 5V DC source to verify .
You mention some time the device can conect the Vin to Vout , Is that possibale some noice disturb device…
Brian Willoughby said: so I assume that +Vbus detection is not applicable.
The ID pin is sometimes not used such as on the ICDI and it doesn't know if GTO is the power source, hate that!
So your +Vbus supplies power to USB device in host mode but PQ4…
I am sorry, I meant tps2052, but I mixed the two up in my previoud post.
From what I know, setting JP1 to Boosterpack will leave out the current limiter tps2052 and feed the 5V from the boosterpack to the tps73733 LDO, so the external source could not…
Other Parts Discussed in Thread: TPS2052B , TPS2052 Hello Amit,
My design calls for powering a target using OUT2 of the TPS2052B regulator. The target, a damaged memory card, could 1. draw too much current or 2. be shorted to ground.
I'm attempting to use…
Hi Arden,
Your device, in your case a flash memory, need to be self-powered in order to function as a host, this is because PB1 are not able to supply enougth current to power up your flash memory, please read 2.1.2 USB Connectivity in spmu296, furthermore…
