Hi,
The datasheet page 15, 8.3.4 Watchdog Timer (WDI) contains the following information:
”The watchdog timer can be disabled by disconnecting the WDI pin from the system…
Part Number: TPS3820 Hi,
The following thread had a status of "Resolved," so I created a new thread. It has the same content as the last question I posted, but could you please check it?

Part Number: TPS3820 Other Parts Discussed in Thread: TPS3823 , TPS3828 , , TPS3824 Hi,
In the same state as the question in the following thread, is it correct to recognize that after /RESET=Low is fixed (Latch), /RESET is released by turning off the power…
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 Other Parts Discussed in Thread: TPS3823 , TPS3828 , , TPS3824 Hi team,
In the datasheet, it says:
"If this behavior is not desired, place a 1-kΩ resistor from WDI to ground. This resistor will help ensure that the TPS3820, TPS3823…
Part Number: TPS3820 Other Parts Discussed in Thread: TPS3823 , TPS3828 , , TPS3824 Hi team,
My customer wants to disable the WDT and set /RESET to high when read/write event at MCU.
In the datasheet, it says that /RESET will be LOW for td when there is…
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,
Andreas
