#93388 - why, oh why Responding to: ???'s previous message |
why, oh why is it so difficult to make someone understand that many companies make supervisor chips, not becuase they enjoy it, but because designers see the necessity of them.
On shorting a jumper my reset is connected to a simple RC and while on shorting to the other jumper reset is connected to a watchdog circuit of a monostable multivibrator of 74HC123 One shot in the foot or a RC, youve got to be kidding. If you are doing industrial units you have two options a) use a proper supervisor or b) find another job. Brownout Level Select is set in such a way that Brownout reset occur only1```````` if supply goes below 2.5V i. what does the "brownout happened" bit say after a "noise reset" Now since this instrument is to be used in Industries, it should have good noise resistance. To check this by placing a contactor near my controller and switching it. It was giving reset on every switching of the contactor. What else can be done to solve this problem……..? 1) GET RID IF THE CRAP "RESET CIRCUIT" 2) check if the brownout bit is set. Erik |
