Part Number: TPS3899 Hi,
Does the CTS signal is modeled in the spice model?
When I perform the a simulation I see that the RESET_B is asserted when the SENSE pin goes below VT- without the delay set by the capacitor on the CTS pin (300nF for minimum of…
Part Number: TPS3899 Hi team,
My customer design TPS3899 and Use SENSE pin to do Push-Button function.
Now they would like to implement longer tD-SENSE time up to 15sec at least. But it seems it is difficult to achieve.
So do you have any suggestion for…
Part Number: TPS3899 Hello team,
Our customer is considering driving digital transistor with SVS such as TPS3899.
Is it ok to use SVS in order to drive digital transistor ?
Please let me know if there any concerns and your proposal.
Thank you and best…
Part Number: TPS3899 Is there a specification for the minimum period of voltage input to the SENSE terminal of TPS3899? If there is a minimum value in the specifications for how long the voltage can be detected below the threshold value, please teach. …
Hi Alfred,
They can add a simple RC network on the input of the VDD to filter out the pulse noise. Do you know if they have a capacitor near the VDD pin for some kind of local bypass?
We do have a new part (TPS3899 - www.ti.com/.../tps3899.pdf) that has…
Hi Oliver,
Unfortunately, we do not have any p2p part like the TPS3808 with push-pull output.
I am not sure if it helps but we do have the new TPS3899 that has the SENSE feature and push-pull output. This part has reset delay but it also has sense delay…
Other Parts Discussed in Thread: TPS3808 , TPS3899 Hi,
I'm finding a reset IC.
VDD : 4V
reset time : 10s
I saw the TPS3808 but it doesn't support 4V supply voltage.
Hi,
Base on your application, you can try the TPS3899 or TPS37x. Both of these parts have a voltage threshold and frequency detection. Both of these parts do not need I2C. Have you check to see if any other GPIO based solutions can work for your application…
Part Number: TPS3805H33 Other Parts Discussed in Thread: TPS3899 , TPS3808 , TPS3890 , Could you provide ESD Ratings (ESD HBM Level and ESD CDM Level) of TPS3805H33? It is not written in the datasheet.
Hi Dimitry,
We cannot edit the prop delay on the TPS3808.
We do have an alternate device that can help. The TPS3899 has a sense pin that has a programmable "sense delay" which can be increased to 1s before reset goes from high to low. Would this work…
