Other Parts Discussed in Thread: TPS3823, TPS3820, TPS3824
Dear Team,
To develop our new project, we are going to apply your TPS3828 to our desing.
Before we apply it, we have a couple of some questions.
[Question 1] - If WDI pin is in Hi-Z, then what's status of /Reset pin with pull-up resistor though VCC ?
When we connect JTAG to our board, All GPIO of MCU is going to be status in Hi-Z.
So, MCU is going to not send clock to TPS3828 and WDI pin will be in Hi-Z.
At this time, /RESET pin does not assert as the below?
[Page 11 on TPS3828 datasheet]
"If the WDI pin detects that it is in a high-impedance state, the TPS3820, TPS3823, TPS3824, or TPS3828 will generate its own WDI pulse to
ensure that RESET does not assert."
[Question 2] - What's VCC range of /Reset pin with pull-up resistor?
We want to connect power supply(12V) to this pull-up resistor.
Is OK or not?
If it's not, please let me know range from min. Voltage to Max. Voltage?
