Exactly... That's where I get the doubt. The low ohm resistor is going to behave in the same way when there's a short, as well as in the normal solenoid case. I would like to know if there's any difference in voltage behavior in the low ohm resistor
Thanks,

Hi Mitra,
There's a voltage source with a current limit resistor to the left. This, in case SHORT, allows 6mA to flow through.. but, in case of A, I am unable to predict the o/p.
Please give a second look at it.
Thanks,
Pawan
Hi Mitra,
Thanks for the reply. guess I am getting clearer....
can you please tell what the voltage at A would be when the attached circuit? The answer would make my idea clear.
Thank you,
Pawan
Hi BradtheRad,
Thanks for the reply.
I wish to know how Solenoid controller IC's detect this. Not necessarily due to a defective solenoid, Accidentally, if a wire comes in parallel to the load(solenoid), the IC senses this and turns the circuit off. I would like to know how this happens.
Let...
Hey Friends,
I am not clear with this, correct me if i am wrong:
A solenoid is just a copper wire with a lot of turns. So, after a few milli seconds, the solenoid almost acts like a wire.
If this assumption is true, how do we detect/distinguish between a Short to Battery and a Normal...
Hi Friends,
I couldn't give a valid reason to someone who had asked me this.
Why can't SPI be standardized to one CPOL and CPHA? having 4 different modes creates more chaos. Is there any logical reason for which these four modes exist.
Compared to SPI, other protocols like I2C, UART or CAN...
Hi Friends,
I have a Segmented LCD with 8 digits and am wanting to interface it with an MSP430 eval. board. On opening it up, I was left with a glass pane terminating as a connector. So, There is no scope for soldering. I ended up in thinking for alternatives. That's when I got a series of...
Hi MrCarlos,
Thanks for the reply.
Segmented LCD's unlike 7 Segment Display requires AC to drive each digit. Continuous/DC between any COM and SEG pin would ionize and destroy the LCD.
few variants like MSP430F413 have a built in LCD driver, which takes care of providing the AC drive...
Hi MrCarlos,
I did find the library in proteus 7. It's a simulation model of Varitronix V402. Unfortunately, The MSP-430 models included do not have LCD module.
This is just for an update.
Thanks,
Pawan.
Hi MrCarlos,
Of course, I will need a real hardware. Just wanted a simulation model so that it wouldn't be affected from my silly errors (like applying DC across seg and com.) I could see the pdf. seems like a proteus model you've created. If yes, thank you. I will get back to you after...
Hi,
I need the proteus model for any segmented LCD (1,2,4 or 8 digit(s)).
I would like to interface it with the built in LCD driver module of MSP430. This is a hobby project to fiddle an old product.
I did some google search but I find only alphanumeric display/7 segment simulation related...
Excellent! Thanks for the help friends.
I had come across the TI's link you had shared KlausST. And you were right, I had an assumption that the comparator's the first stage of the ADC.
The Maxim article link shared by crutschow and the AD simulation link shared by schmitt trigger are superb...
