Part Number: TPS3705 Dear e2e,
Could you confirm that WDO/ is a high impedance output?
My customer would need to latch the WDO/ to not get the cycling phenomena (explained here )
Do we have other supervisor? or other trick than the App Note SNVA837? …
Part Number: TPS3705 Other Parts Discussed in Thread: TPS3851 Hello,
If I understand well, /WDO doesn't stay low when there is no signal on WDI. So the timing diagram for /WDO on the figure 7.1 is false.
The following sentence : " This event also…
Part Number: TPS3705 Other Parts Discussed in Thread: TPS3823 , TPS3851 Hi Team
Could you check my questions regarding the MR and PFI/PFO pin when not being used?
MR pin
1. Is it safe to leave it open when not being used? (I checked the block diagram and…
Part Number: TPS3705 Quick question on WDO functionality... Assuming all else is good in the system, when WDI stops toggling, and WDO is activated (driven LOW)... will WDO remain low indefinitely, until WDI begins to toggle again? The datasheet says that…

Hi Team,
The datasheet has specifies that minimum pulse width at WDI pin is 100nS. The customer wants to use 25MHz CLK to feed watchdog. They have two questions below. Could you please help give your comments? Thanks!
25MHz CLK…
Part Number: TPS3705 Hi team,
My customer reported a problem of TPS3705-33DR. In customer's equipment, the watchdog needs to be disabled in some condition. They disable the watchdog by floating WDI input of TPS3705 through a jumper. The WDI pin is connected…
Part Number: TPS3705 Hi there,
My customer is using WDO to pull down MR to reset the processor itself which stopped feed WDI. In the WDO output, there is a 0.1uF capacitor that prevents MR pulled low to its threshold to trigger reset. After removing the…
Part Number: TPS3705 Hi,
Please confirm the output type of each pin on the TPS3705. The selection guide shows Outputs as Active Low push pull but I could not find any thing in the datasheet that confirmed the push-pull vs open drain output types.
Thanks…
