Part Number: TPS3897
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…
Part Number: TPS3897 In the datasheet (April 2015), section 7.5 Electrical Characteristics, it provides a Typical Hysteresis Voltage of 5 mV but no min or max value.
At a minimum, I need to know the Maximum Hysteresis Voltage (over operating temperature…
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…
Part Number: TPS3897 Hello E2E,
Is there any concern if we have Vsense on before VCC is applied for TPS3897? Or are we okay as long as table 7.3 is met regardless of if the device is powered or not?
Regards,
Russell
Part Number: TPS3897 Hi Team,
My customer is wondering if Enable pin of TPS3897 can be used for manual reset now.
Do you have any concerns such the following use case?

Part Number: TPS3897 Hello expert,
May we know if there is any sequence requirement for Vcc and EN? We checked for datasheet and EVM user guide, EN and Vcc are connected together directly. May we know if it is okay for use? Thanks a lot!
Best regards…
Part Number: TPS3897 Hello expert,
Customer has two questions about TPS3897 on the delay time setting. According to datasheet equation (2), it seems like it is not match about below table value. And also, do we have maximum delay time limitation? Customer…
Part Number: TPS3897 hi,
My customer wants to design a pulse generator and the pulse is around few nano second.
also, the pulse width is adjustable.
I found the app note below. but it's for mini second range.

Part Number: TPS3897 Hi,
We got a question from the customer about TPS3897. Could you help us?
[Question] Are there any voltage level requirements between Vcc and Vsense? They are concerned whether Vs voltage allows to exceed Vcc voltage, or not.…
Part Number: TPS3897 Hi team,
My customer is using the TPS3897 now, and the sense input negative voltage will arrive -0.6v, over the Absolute Maximum (-0.3v), whether it has risks here? Thanks.
