Hi Sila,
Thank you for your support. I understand that TPS3897A-6P-EVM047 works as expected. Please let me know if you find any problems with the model.
Best regards,
Taka
Part Number: TPS3897 Hello team,
Is there any data for input impedance of VCC?
My customer would like to use resistor divider as supply to VCC.

Other Parts Discussed in Thread: TPS3899 , TPS3760 Hello, For an MCU based design,TPS3897ADRYR is used to control the Hardware reset of the MCU, My intention is if the sense input is low for 10s or more the the reset out of the TPS3897ADRYR should be asserted…
Part Number: TPS3897 Hello:
Schematic is the following:
Timming is the fillowing:
My question is the following:
1. Whether output waveform will link with VCC ramp up Tr or not? If the ramp out is very fast, for example VCC going to 3.3V within 20us…
Part Number: TPS3897 Hello
When consider the delay time of TPS3897, I think the parasitism capacitance of pin of CT of TPS3897 need to be considered.
I would like to know the value, is it 1~2pf?
Thanks!

Hello,
We are using the TPS3897P with tpd(r) set to 5sec via capacitance.
When the device is powering up, we have SENSE coming up ahead of Vcc, then the ENABLE goes high about 200ms after VCC.
Since ENABLE is after SENSE and VCC…
Hi Paul,
Since the TPS3897 DS has provided the Vit+ for an under voltage detection device.
The highlighted values are the min, typ, and max for the Vit+, to de-assert RESET.
For the Vit-, Vsense to assert RESET, Vit- = Vit+ - Vhyst.
Vit-(min) = .49V…
Part Number: TPS3897 Hello TI expert
In AN snva845 figure 3, a JFET is used to mitigate the indeterminate output voltage.
I wonder why a JFET is used here. What's the key parameter for the JFET?
Is it possible to change it to MOSFET?
Thanks in advance…
