Building a fault detection device.
Once fault is detected device should not resume to normal working condition until and unless POWER is switch off for 30 Seconds.
If power is restored before 30 seconds ( after switching OFF ) it again goes in Fault state.
Device do not contain any battery...
Hey Tehmid,
Thanks for the reply.
I am sorry for the little vague description.
Actually my signal span is -3.3V to 0 +3.3V Dc which is expected to follow PWM of 20kHz.
I want to block negative part of the same and intend to use Schottky Diodes ( A ADC Pin and Ground ) for the same as at very...
Hi..
One of the signal which is ( -3.3V to 0 ) need to clamp to level of 0V.
I can do that using the level shifter by using a voltage divider pulled up to Vref; but need to implement some other technique.
Basically I want to block (-3.3V to 0 ) range to ADC and allowing only ( 0 to +3.3VDC)...
Re: facing problem in choosing low cost led display
See there are plenty available but depend on application.
You can go through this..( only for low cost option..)

LCDs are recognised by the segments they glow.
If you want to find a similar LCD you need to have segment this LCD used to glow. All segments.
This you can draw by hand also, just try to remember where which 7 segment / idetifiers / icons used to glow??
If you can post that someone can...
1. To sense presence of current you can look at the hall effect sensors. But it will be a mechanical challenge to create a air gap and insert a small PCB along with sensor inside.
+ if you have specific current cut off to sense it will be difficult in mass production.
2. Shunts are not...
