Part Number: TPS3840-Q1 Tool/software:
Hi,
In the data sheet there are the formulas to calculate reset delay time (max and min values):
But in the electrical characteristics I didn’t find the information about tD (no cap, min):
Could you please…
Hi Nitesh,
For external hysteresis, internally what we need is the Sense feature as in high level of block diagram. For TPS3840-Q1, the VDD and Sense pins are combined. So it should work.
I need to check for the model. I'm not sure if we can simulate…
Part Number: TPS3840-Q1TPS3840-Q1 tSTRT + tD time is measured differently from the datasheet value.
The datasheet shows 400us as the maximum value.
When I actually measured it, it came out about 10 ms as shown below.
Please find the cause why. …
Part Number: TPS3840-Q1 Hi Team,
I am planning to use TPS3840DL16DBVRQ1 part in my design for automotive application. The purpose is to monitor the DC-DC converter output voltage and act as power good circuit.
My voltage to be monitored is 6V and The…
Part Number: TLV840-Q1 Other Parts Discussed in Thread: TPS3840-Q1 Hi team, May you help me understand what's the main difference between TLV840-Q1 and TPS3840-Q1? Why TLV840-Q1 is cheaper, and in what kind of situation TPS3840-Q1 is required? Thanks…

Please inquire about this part number :TPS3840-Q1
1. Currently, an open-drain structure is used. (3840DL30XX)
However, the pullup power of the RESET pin rises from L to H after about…
Part Number: TPS3840-Q1 Hi~ Team.
Customer has some issue on reset delay of TPS3840-Q1.
Do we have real measurement waveform like Figure 4 VDD-RESET timing diagram?
It may help to understand.
Thanks.
Part Number: TPS3840-Q1 Hello team,
I kindly request you to provide the PSpice Model of TPS3840DL20-Q1. In PSpice for TI, this threshold value model is not available.
Part Number: TPS3840-Q1 Other Parts Discussed in Thread: TPS3803 , , TPS3803-Q1 , TPS3840 Hello team,
Previously we were using TPS3803/3808 devices which had a separate sense pin and manual hysteresis was added from Sense to Reset Pin.
In TPS3840-Q1, since…
