Part Number: TPS2490 Tool/software: Hello! I need help!
I have 3-chanel switch, based on TPS2490DGS part. 2 channels are ok (gate control shuts off) and on the third one gate control signal oscillates with 400us if I test short cut protection. Mosfet…
Part Number: TPS2490 hello
i have used this part for current limiting short pulses of about 5A for about 30ms . ive used this part in this appication in the past with a few of this pulses one after another have not had a problem.
in one of my design…
Part Number: TPS2490 Tool/software: Dear,
TPS2490.
I have an application where after normal inrush procedure, the current flow will be reverse through the sense resistor and mosfet. So current flows from Vout to Vin.
Hence the SENSE pin goes above…

Part Number: TPS2490 Tool/software: Hello Team,
Greetings !!!
We are using "TPS2490DGSR" in our design for limiting the current for brakes. Attached the snap of the circuit for reference.
To address the EOL, the MOSFET Q13 is replaced in the latest…
Part Number: TPS2490 Hi Team,
My customer has some queries regarding the §8.2.2.3 : Power Limit Selection of the IC TPS2490 mentioned below:-
As you see below, first you select the Plim,min with Vprog x Ilim x 10.
Then you size the resistive divider…
Part Number: TPS2490 Tool/software: Hi,
I am wanting to understand the voltage constraints in the TPS249x_8x_Design_Calculator_REV_B.xlsx calculator for Target Under - Voltage.
The comment in the cell states "This threshold must be between 2.9V and…
Part Number: TPS2490 Tool/software: The layout guidelines for the TPS2490 provide the following: "The ground connection for the various components around the TPS2490 must be connected directly to each other and to the TPS2490's GND pin, and then connected…
Part Number: TPS2490 Tool/software: I have an implementation of the TPS2490 hotswap controller as shown below:
I've been experiencing failures of the Q2B/Q3B FETs during operation when starting into a short circuit and sometimes when applying…
Part Number: TPS2490 Tool/software: I'm watching the tutorials for the TPS2490 controller design spreadsheet ( https://www.ti.com/video/4609077122001 ) and they mention bugs in some cells which may not populate.
I have some cells which simply say "NA…
