Part Number: TPS3820-Q1 Tool/software: Hi,
Datasheet of TPS3820-33 specifys that /RESET asserts "td" (time delay) after rising of VDD
Is "td" also applied between rising of /MR and rising of /RESET?
Thank you
Part Number: TPS3820-Q1 Other Parts Discussed in Thread: TPS3820 Tool/software: Dear experts,
I'm trying to work with the watchdog TPS3820-Q1 and a NXP microcontroller. The circuit is shown in the figure below:
The signal WDI_UC is a GPIO from the…
Part Number: TPS3820-Q1 Tool/software: My customer reported an urgent issue that they found TPS3820-Q1's t tout (Watchdog time out) changed permanently after they implemented the high temperature test (100 degree).
In the below waveform, reset was triggered…
Part Number: TPS3820-Q1 Other Parts Discussed in Thread: TPS3820 Hi ,
When the PWM signal input the WDI pin, TPS3820-33QPDBVRQ1's WDO pin keep low. That is correct?
Part Number: TPS3820-Q1 Other Parts Discussed in Thread: TPS3820 Hi Team,
The figure below shows the circuit and measurement waveform of TPS3820, and the questions are as follows: 1. When the WDI pin has PWM input, the output voltage of the WDO pin is LO…
Part Number: TPS3820-Q1 Other Parts Discussed in Thread: TPS3820 Hi,
My question is about TPS3820(non-Q1).
If DWI is fixed at High when/RESET=Low(Active), is there a problem with the device?
I think there is no problem, is this correct?
Best Regards,
…
Part Number: TPS3820-Q1 Hi Team,
Need suggested /RESET series resistor circuit/resistance value for reference.
In addition to the MCU, /RESET also control the Q8 transistor, is the I/O current sufficient for resistor matching? resistor how to adjust ohm…
Part Number: TPS3820-Q1 Dear TI team,
can you please tell me the difference between the TPS3820-50 Q DBVRQ1 and the TPS3820-50DBVRQ1 G4
Thanks in advance,

Part Number: TPS3820-Q1 Other Parts Discussed in Thread: TPS3820 Hi,
This was used for a mass production design.
When applied to new solutions, the feed dog Pulse width change From 10ms to 7ms，But the tw Pulse width at WDI is 100ns in datasheet，7ms>>100ns…
Part Number: TPS3820-Q1 Hi team,
Since 3820 reset pin is push-pull output, and the MCU my customer use will force the pin into low during debug mode, here are some questions(customer want to know if there is risk):
When GPIO forces the reset pin into…
