Part Number: TPS3823-Q1 Tool/software:
Original part number: EM6323LXSP5B-2.9+ ( Supervisory circuit with watchdog ) moving to TPS3823-33DBVR.
So please let us know what are all the generic test to be performed during design validation.
Thanks…
Hi Elyse, Thanks for your question!
I want to let you know that there is no attached specs to thread but I was able to find the datasheet online.
TPS3823-33DBVR seems like P2P with APX823-31W5G-7. The only thing I need mention is the threshold is…
I'm trying to understand a spec in the datasheet, and it seems to be contradictory.
Basically, it's how low a voltage will this chip work and keep my MCU's reset pin asserted.
The way this is spec'd it says down to VDD=0.4V (based on the footnote…
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…
Part Number: TPS3823 Hello guys,
One of my customers uses TPS3823-50DBVT for their current mass-production.
Recently, they received PCN(PCN# 20230830002.3) which says TPS3823-50DBVT will be EOL. (TPS3823-50DBVR will be not EOL) At this moment, they…
Part Number: SN74HCS32-Q1 Other Parts Discussed in Thread: INA148-Q1 , TCAN1042-Q1 I inquire about the functional safety FIT(Application FIT Rate) value for the device below.
Standard is SIEMENSE SN29500-2.
(it is not a request for a JEDEC-based technical…
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…
Part Number: TPS3823
There is an abnormal behavior on our circuit，and the phenomenon is not easy to reproduce。
Currently we set WDI to high-impedance , we purpose to disable the WDI timer from our system.
I found the problem of adding capacitors…
Nicola,
There is no way to disable TPS3813-Q1 unfortunately. TPS3850, TPS3851 or TPS382x family (TPS3820, TPS3823, TPS3828, TPS3824) will work or the devices you mentioned in the app note will work.
