The schematic above is the expected effect I want to achieve, but the following is the result I tested out.
asms_1, wd_0. reset flashing asms_1, wd_ floating (there is a 5v pull-up here). reset flashing asms_1, wd_…
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 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 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…
