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…
Part Number: TPS3840-Q1 Other Parts Discussed in Thread: TPS3840 , Hi Team,
I'm trying to calculate the voltage divider for load dump of 12V battery application. I refer to the application note(SNVA864), but it does not meet my requirements. (undervoltage…
Part Number: TPS3840-Q1 Hi,
The customer said that the start up current of TPS3840Q1 was too large in the design, and 800K resistors need to be connected in series in the designed signal link, but TPS3840Q1 cannot start to work with the 800K resistors; In…
Part Number: TPS3840-Q1 Other Parts Discussed in Thread: UCC27517A-Q1 Hi,
FIT rate of TPS3840DLxx seems 0.4. Can you please tell me something about the failure mode distribution? In particular, can a failure mode of "output short to VDD" happen to an…
Part Number: TPS3840-Q1 Hi,
datasheet 8.2, functional block diagram seems weird:
Nothing can pull CT down to GND.
Do you wanted to mean something with CT pin comes from the drain of the left side N-ch MOSFET; whilst the source of that MOSFET is at GND…
Part Number: TPS3840-Q1 Hi team,
I am designing MCU reset circuit using TPS3840-Q1 as below.
VDD = button battery <4.5V
Vthreshold = 2.2V
V pullup = 1.8V
Pull up register value = 10kohm
Output I/F = Active Low Open Drain
1. Could you advise the…
Part Number: TPS3840-Q1 Other Parts Discussed in Thread: TLV840 , TPL5010 Hi Team,
I know our reset IC could achieve delay function but customer would like to have below extra function, do you have any idea how to achieve or any IC could meet the requirement…
Part Number: TPS3840-Q1 Other Parts Discussed in Thread: TPS3840 Section 7.7 of the datasheet shows several figures (Figure 7 through 9) of supply current vs supply voltage at different operating temperature points.
All of these curves do not show a spike…
Hi Dino,
Please find my answer in below.
The relation between Maximum sourcing current (IOUT(Source)) and minimum high level output voltage (VOH( min )) :
In terms of your question on the relation between Maximum sourcing current (IOUT(Source)) and High…
Part Number: TPS3840-Q1 Hi TI-team
Please tell me the behavior of IC when each pin is open and adjacent pins are shorted.
Also, what happens when the CT pin is shorted to GND ?
Best Regards,
