Part Number: TPS3851-Q1 Dear, Sir.
My customer is considering to apply TPS3851-Q1 for their system.
At this time, they are asking about the current definition for SET1 $ WDI pins, how much?
On the datasheet, I can see the low # high level threshold,…
Part Number: TPS3851-Q1 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hi Team,
My Customer is asking if we can provide them the TINA Reference Design for TPS3851-Q1. I tried to search it on our repository but this is not…
Part Number: TPS3431 Other Parts Discussed in Thread: TPS35-Q1 , TPS3435 , TPS3851 , Hi team,
Could you confirm whether the WDI pin can support 16MHz?
Are there any devices whose WDI pin can support 16MHz? Do you think devices below can support it?
TPS35…
Part Number: TPS3851-Q1 Hi team,
I would like to know the maximum VOL of TPS3851G33EQDRBRQ1 at VDD=3.3V.
VOL maximum is specified at VDD=5.0V and Ireset=3mA and is 0.4V.
Since the VIL max of the target IC's reset pin is 0.35V, I would like to know if…
Part Number: TPS3851 The WDO of TPS3851 is used with feedback to MR. If so, I have a few questions.
Q1.In this circuit, when WDO is asserted and MR goes "L", RESET is asserted and WDO is in a high impedance state.
The data sheet indicates that…
Hi Jimmy,
Really appreciate the clarification, the TPS3823-33QDBVRQ1 is an option to consider. However I would recommend the customer to also look at our latest watchdog device such as the TPS3851-Q1 . Hope this helps, else please let us know what else you…
Hi Jim,
So looking at the MAX device, it seems that they can theoretically support a large delay like 5s, but we rarely see requirements for that long delay. Even in their graph for reset delay vs capacitance, the maximum they show is about 2s. I think…
Hi Ochi,
The TPS3851-Q1 is the standard watchdog variation of the TPS3850-Q1. You should be able to switch this and use it just like a standard watchdog. Can you switch to this part?
Thanks,
Abhinav.
Shinji,
Does Vsense monitor only undervoltage? If so, I think TPS3851-Q1 is the correct device as this is undervoltage monitor with standard watchdog.. This will require external resistor divider on VDD because there is no fixed threshold for TPS3851…

Hi,
I am looking for a watchdog timer which would give an output (high or low) when input pulses meet timing requirements. When Input is low, output should go and stay in a high…
