Part Number: TPS3890 Hi Team,
My customer has tried to figure out which capacitor to choose for CT. On page 4 Cctmax=22uF and on page 11 it is CTmax=26uF
However if U calculate tpd(sec) from 0-26uF (see in plot below), tpd goes up to 58sec at Cct=26uF…
Part Number: TPS3890-Q1 Other Parts Discussed in Thread: TPS3890 , I have a question is about component TPS389050GQDSERQ1. We have the following datasheet for it: tps3890-q1-Feb_2018.pdf (SBVS303B –MARCH 2017–REVISED FEBRUARY 2018).
Additionally…
Part Number: TPS3890 Other Parts Discussed in Thread: TPS3808 Hi,
I have a design that is using the TPS389001 with the recommended voltage divider circuit on the SENSE pin to set the voltage threshold that I want to use.
Unfortunately, given current supply…
Part Number: TPS3890 there is 1pcs chip TPS389030DSET, it is a reset chip, it works properly during PCBA function test, but when we assembled it into our optical module, the whole board did not work, after failure analysis, we found chip TPS389030DSET…
Part Number: TPS3890 Hi Team,
My customer is planning to used TPS3890 as solution and wanted to ask about this part's tPD(f) , per d/s , CT pin can used for adjust the delay time by using different cap value, but it's only shown that tPD(r) is adjustable…
Part Number: TPS3890 Other Parts Discussed in Thread: TPS3820 Team,
Could TPS3890 meet our requirements as below image? (
. As input is pulled low more than 10s, the output can have a short low pulse. The short pulse is used to disable another IC.
) …
Part Number: TPS3890 Hi Team,
Do we have reset IC could meet title requirement?
When input is pulled low more than 10s, the output can have a short low pulse.

Part Number: TPS3890 Hi,
If sense voltage reaches VITP before CT voltage hits VCT as following picture, How does CT pins and /RESET pins works?

Part Number: TPS3890 Hello Team,
does the TPS389018 have problems if the MR pin get 3.3V while Vdd is not yet getting 3.3V?
In particular Vdd and MR voltages, come from two different power supplies.
MR gets for short time 3.3V at low impedance (without…
