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!
Jeff
Hi Hansook,
Thanks for pointing out this problem on the datasheet. We will change the timing diagram in our next revision since beginning part causing misunderstanding.
Please look at the zone1 to understand correct td time delay behavior. As long as Vdd…
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…
Hi Hansook,
I would like to clarify a few key details as well as provide an update for you:
The TPS3840DL30DBVRQ1 under voltage threshold is designed to operate at 3V threshold without the need for external components.
The 30us detection delay in 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…
Part Number: TPS3840-Q1
Dear team,
TPS3840-Q1 is Functiona Safety-Capable device. so we can see FIT rate and FMD report at ti.com.
But the customer want to get FMEDA report and Functional safety manual to get SIL 2(IEC61508) grade for their application…
