Part Number: TPS3840 Other Parts Discussed in Thread: TLV840 , TPS3808 Tool/software: Hi,
We have designed a complex circuit in which we use the TPS3840PL30DBVRQ1.
After testing the circuit, it is fully functional.
In this circuit we use the MR pin to…
Part Number: TPS3840 Tool/software: We have an issue with this reset generator.
Below you can see the TPS3840 is always powered at a constant 3.3V. The 12V is always on, thus the 3.3V zener always works.
The MCU is at 3.3V and commands the /MR pin. When…
Part Number: TPS3840 Hello:
Please assist in conducting a review of the MC project schematic about TPS3840.
Due to the urgency of the project, we hope to receive feedback as soon as possible
Part Number: TPS3840 Hi
TPS3840 in my system have VDD drop issue durring some voltage level.
But thershold level VDD is stable, and reset output is functional.
And we don't plan to change resistor value. and the system design don't care " Vpor status…
Part Number: TPS3840 Hi,
May I know there have TPS3840PH16 device can support?
I found it in datasheet table 3. But can't find it in both PACKAGE MATERIALS INFORMATION and TI website. thanks!
Thanks!

Part Number: TPS3840-Q1 TPS3840-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 Hi,
We have used TPS3840PL28DBVR in our custom board design. We have designed the part as mentioned below.
We have gradually decreased the input VDD (28V) to 0V and captured the output RESET performance. But during the range 18.5V…
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: TPS3840 Hi,
In our design, TPS3840PL28DBVR has been employed. The operating voltage of our system is 28V. Employing resistor division, the IC receives an input of approximately 4.5V under standard operating condition. However, when subjected…
