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 Team,
Would you like to help me check the Ct range of tps3897? maybe we have one project need to set the delay time to several second, I am not sure this part has problem or not if using very large Ct.
Thanks,
Antony
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…
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 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?

Russell
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…
Hi Ning,
Ah yes, asking two questions right after each other isn't the best thing to do. Here are the answers;
1. The yellow waveform is connected to a TPS3897's SENSE_OUT. It has a sense delay of 5 seconds, so the first 5 seconds, the circuit is…
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.
