Part Number: TPS25990EVM Other Parts Discussed in Thread: TPS25990 Hi
In the TPS25990 EVm, the SBR10U45SP5 (SUPER BARRIER RESTIMP) is connected between the VOUT and the gnd. What is the purpose of your use?
Thanks
Part Number: TPS25990EVM Hello,
I am trying to setup this EVM for a customer, but I am unable to connect. I open the GUI, follow the hardware setup instructions but when the GUI starts scanning for devices no addresses are found. I am unsure of the USB2GPIO…
Extremely sorry for the delay.
This was a known issue in the previous version of the TPS25985 silicon, which is populated on the EVM.
Can you please make the following change in the TPS25990 device through the TPS25990EVM GUI?
This will solve the problem…
Are you using TPS25990EVM?
If yes, this EVM consists of TPS25900 and TPS25985 in parallel. GPIO3 must be set to SWEN. GPIO2 or GPIO4 should be used as a comparator output. GPIO_CONFIG_12 (E1h, Read/Write Byte) and GPIO_CONFIG_34 (E2h, Read/Write Byte) registers…
Hi Jun,
We tested TPS40400EVM-351 with TPS25990EVM by connecting the SCL and SDA lines of the respective EVM's together. Using a single USB-TO-GPIO2 USB interface adapter evaluation module, my PC can interact with both GUIs, Fusion GUI and TPS25990 GUI…
Please see the below waveforms. The UVLO protection was completely disabled in the TPS25990 by two ways:
EN/UVLO pin is connected to VIN through a 1 MΩ resistance. A 1 μF ceramic capacitor is connected across the EN/UVLO pin and GND. This helps…

Hi Team,
We are facing a startup issue in our TPS25990-based design.
Instead of 12V in the E-Fuse output, we are getting only 2V.
We have probed the waveforms. Attached are the waveforms, schematics, and TI E-Fuse calculation sheet…
