Part Number: TPS3840 Other Parts Discussed in Thread: LM393 Hey E2E Design Support,
Recently we have started testing with TPS3840 for RESET management and Voltage Monitoring.
We have LM393 for Fine-tuned voltage management. It has Open…
Part Number: TPS3840 In case of an overvoltage situation, how can the downstream power tree be disconnected to protect it from such overvoltage? Can reset ICs not only sense the overvoltage but also drive a PFET switch to turn it off?
Part Number: TPS3840 I am using the TPS3840DL49DBVR to monitor a 12V power supply for power down. I am using similar circuit to one on Figure 52. The difference being I have a larger resistor divider and no CT cap for the smallest reset delay. The circuit…
Part Number: TPS3840 Dear E2E Design Support,
Using the open-drain version of this voltage supervisor chip, can I assume the RESET pin high-impedance when the chip is not powered? As for the background of my question, in my application it is a valid possible…
Part Number: TPS3840-Q1 Other Parts Discussed in Thread: TPS3840 Hello team,
I have a question about RESET pin behavior
If the VDD slew rate is very slow and the slew rate is longer than Tstrt+Td, What is the behavior of nRESET?
I guess the behavior will…
Part Number: TPS3840-Q1 Hi support team, I have a question about Revision History of SNVSBA1B.
The following changes cannot be confirmed in Revision A and Revision B.
Is it a change from Original to Revision A?
Part Number: TPS3840 Hello Team.
I would like to know about TPS3840DL29DBVR
Tp_hl shows 30usec (max) at Ta=-40degC to 125degC.
I want to know its spec at Ta=-40 to 85degC
Do we have any referential data to provide ?
Any advice will be appreciated.
Part Number: TPS3840-Q1 Other Parts Discussed in Thread: TPS3840 Hi Team,
Our customer would like to confirm if the equations 7 and 8 are correct because the Vrail trigger voltage will be lower than the threshold voltage if we compute using those equations…
