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: 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: 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: 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…
Part Number: TPS2490 Tool/software: I'm not seeing any information in the TPS2490 datasheet about reverse current operation.
The controller will begin to limit the gate drive to the external high side NFET when the current sense voltage is +50mV measured…
Part Number: TPS2490 Other Parts Discussed in Thread: CSD17570Q5B Tool/software: We use TPS2490 to power on a 10mF load. I have used the design calculator, but I get that the minimum slewrate is higher than the max slewrate. Does this mean I can not used…
Part Number: TPS2490 Tool/software: On the Datasheet §8.2.2.1 p. 20 there is an explanation on how to add parallel resistors to change the current limit:
but in the picture, they are named R1 and R2 and in the formula R3 and R4!
how are they related…
Part Number: TPS2490 Other Parts Discussed in Thread: CSD19536KTT , CSD19506KTT Tool/software: Sim_30A_Range_HCV_VI_PBox_REVA.TSC
I'm trying to run this simulation and it's not converging. I'm using the IGC033S101, which I believe is an n-channel GaN…
Part Number: TPS2490 Other Parts Discussed in Thread: TPS2491 Tool/software: Hi team,
I met a TPS2490 issue and hope you could help to give some comments here.
After power up, PG, Gate and PROG pin all keep low. from datasheet, TPS2490 seems latch…
