Hello Jesse,
Thanks for the response. I have one more query about this design. In case if we want to REST controller whenever VDD (VDD ranges from 1.8V to 3.6V) goes below 2.5V should we use TPS3851H25EDRBR in our design?
Part Number: TPS3851 Tool/software: Hello,
We are using your TPS3851H33EDRBR part in one of our design. We were referring the VIL and VIH levels from electrical characteristics. As per the datasheet page no. 5, VIL and VIH for MR and SET1 pins are given…
Part Number: TPS3851-Q1 Other Parts Discussed in Thread: TPS3851 Tool/software: Hi TI experts
I have a question shown as below.
The WDO tRST is only about 100us used in our product as shown in the figure ( blue curve), and the WDO pin is connected to our…
Hi Bokar,
It's very unfortunate that you are not able to swap the chips. That would help us to find the root cause. \ Without specifying where the issue is repeating it's harder to diagnose. Currently we don't know when the issue is repeating. We don…
Part Number: TPS3851-Q1 Hi Expert,
There is a description in TPS3851-Q1 datasheet: when timer overflow, WDO will pull down and generate a reset signal.
May I ask how long the RESET signal will keep? and whether the time tRST is configurable?
Thanks a…
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…
Part Number: TPS3851 Hello, customer ask what the WDT timing is for standard and extended device is when the CCWD cap is not connected. It is different when connected (Table 8-2) but should be same if not connected (Table 8-1). Please check.
Regards, …
Part Number: TPS3851 I am trying to test the WDO behavior in the absence of a falling edge. The WDO doesn't behave as expected when there is no falling edge triggered. I would expect that the signal stays low. Instead, it looks like it follows CWD pin…
