Part Number: TPS3828-Q1 Other Parts Discussed in Thread: TPS3123 Tool/software: Hello,
I am planning to useTPS3828-Q1 and TPS3123 on my designs.
I would like to get a report on anything related to tested radiation data such as total I onizing dose…
Part Number: TPS3123 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…
Part Number: TPS3123 Hi Team,
My customer used TPS3123J12 and found the probelm in the datasheet.
They would like to know what the time slot from D to E showing in below pic. Is it 1us or other?
Thanks!
Albin,
If you want a part like MAX6898, I recommend TPS3890. This is a high-precision voltage supervisor with independent sense pin, programmable delay, and manual reset.
If you need a watchdog timer in addition to voltage supervisor, I recommend…
Takao,
What Watchdog period are you looking for? Typically, the fixed Watchdog devices will be more accurate than the adjustable Watchdog devices because of the capacitor used to program the watchdog period.
TPS3123/4, TPS3128 for lower voltage…
The nRESET assertion time requires 25 us for a reset caused by voltage at VDD. The WDI pin recognizes pulse with width greater than 100 ns. This should give you the timing required to estimate the sensitivity at the moment reset is asserting and a watchdog…
Hi Guy Yater,
Thanks for the response.
When I was going through http://www.ti.com/lit/sg/sszb130b/sszb130b.pdf this document & I found recommended part as TPD8E003.
So now I'm in confusion to use any one of them, Can you please suggest me , which…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
