Part Number: TPS3850-Q1 Tool/software: Dear Team,
As discussed earlier regarding the MCU continuously resetting, based on Texas Instruments recommendation and our analysis, we understood that the previously selected IC (TPS3850G09QDRCRQ1) was not suitable…
Part Number: TPS3850-Q1 Tool/software: Hi Teams,
Please kindly help to review the sch. And help to check the below questions.
1, We are expecting to have 132ms upper threshold (pic1) with 1nf CWD & CRST 4.7nF. But found the WDO reset asserted when…
Part Number: TPS3850-Q1 Tool/software: Hello TI experts,
When using TPS3850-Q1, we add a 100nF capacitor on WDI pin, for noise decoupling. This causes a problem: WDO is asserted occasionally. The rise/fall rate of WDI input is about 55mV/us.
We suspect…
Part Number: TPS3850-Q1 Tool/software: hi expert
i saw the following words in our datasheet which i mark with orange.
how to understand "When RESET is asserted, the watchdog is disabled and all signals input to WDI are ignored."?
from my understanding…
Part Number: TPS3850-Q1 Tool/software: Dear Team,
The connection of Supervisor circuit and MCU is given below. What suggestion could you give us to make it functional? The MCU is STM32L496ZGT3. The pin 25 is connected with the supervisor RESET pin…
Hi Weicheng,
The TPS3850-Q1 has functional safety information provided under the technical documentation tab of the product folder, https://www.ti.com/product/TPS3850-Q1#order-quality . This information has FIT rate and failure mode distribution values…
Part Number: TPS3850-Q1 Other Parts Discussed in Thread: TPS3850
Hi team，
For watch dog IC TPS3850, it shows that the IC failure rate is 25 feet, but for Functional safety requirements, it should be under 10 feet, so does the 25 feet of failure rate…
Part Number: TPS3850-Q1 Tool/software: Hello,
I have an issue using PSpice and I need help to solve it.
ERROR(ORPSIM-15139): Time step = 703.5E-21 is too small in Transient Analysis at Time = .182. Minimum allowable step size = 1.000E-18. The device…
Part Number: TPS3850-Q1 Tool/software: Hi team,
could you help to check what value is the minimum capacitor on VDD pin, from the datasheet, I see the value is 0.1uF. if we can use <0.1uF capacitor?
Part Number: TPS3850-Q1 Tool/software: I inquire about the functional safety FIT(Application FIT Rate) value and failure mode distribution, Gate scale for TPS3850-Q1.
Standard is SIEMENSE SN29500-2.
(it is not a request for a JEDEC-based technical…
