Part Number: UCC2946 Dears:
Could you kindly help to check the value between t5 and t6 as below picture:
Since from datasheet there is no description about the value.
Dear Sirs,
May I have your support to confirm the max reset & watch dog period time ?
Our target is 5 minutes for Watch dog
5 second for reset
Many thanks !

Other Parts Discussed in Thread: UCC2946 , UCC3946 , TPL5000 need a watchdog timer which generates RESET when no input signal is asserted in the watchdog timeout (see the figure below).
Is the ucc2946 device – can it be suitable forthis requirements?…
Other Parts Discussed in Thread: UCC2946 , TPL5000 Hello, I am planning to use the UCC2946 for a purpose slightly different than its intended use. I intend to use it as a fail-safe to disable a laser if the WDI pin has not been toggled for a certain amount…
From the block diagram of the SLUS247f.pdf, I dont see the relation of the watchdog with the nRES output.. The only connection that connects the two are the Q output of the SR flipflop to the NAND gate.. If I look at the timing diagram of figure 4, the…

Other Parts Discussed in Thread: UCC2946 Hi,
I am presently using UCC2946 with a capacitor at pin WP of 680pF. I observe that the WDO remains high while WDI is statically driven to 0V through a 10K pull-down resistor. This indicates that the watchdog is disabled…
Other Parts Discussed in Thread: UCC2946 Hello,
I am looking for a microprocessor supervisor circuit with watchdog, that can produce a 120s (nom) watchdog delay.
We also need industrial temperature range.
The UCC2946 is promising, but the spec doesn't…
