If you have 3.

Hopefully, I was clear in my explanation. Your name or email address: Why does your schematic drawing software produce backwards negative white lines on a black background instead of a normal positive image??

An easier to read schematic: Dec 28, 7. Mar 14, 20, 5, To avoid these issues, you can change your voltage divider to use a voltage below the guaranteed max input voltage.

No, create an dztasheet now. Its purpose is to protect Q1 from too much base current, which is not a problem in this circuit. DC current gain Posted by qitara in forum: Thank you all so much for any input. Here is a screen shot of the circuit, an explanation of my rationale, and the problem I am having.

Also, Vce is listed as 1V here. You datashret need 4mA, so beta isn’t a critical parameter. You didn’t show the entire datasheet page, but I think the DC gain of 70 is a minimum value for that collector current.

Could someone explain this section to me? Do you already have an account? Sep 20, Mar 30, 7, 1, Dec 28, 6. When the voltage across my sense resistor exceeds 4V, 4mA total current, the LMN will output low unbiasing the 2n Dec 20, 10, 1, Dec 27, 3. In this case, something in the 1K to 10K range might help, but I wouldn’t put it in until needed.

You can omit the base resistor. Mar 4, 2, Dec 28, 9. Dec 27, 2. Dec 28, 5. Also can’t you turn off the “chicken pox” dots??

Datasheey serial connections and USB to serial conversion connections are covered. I know I may have to implement some hysteresis into this circuit. Hope this helped, Kevin.

Yes, my password is: I am pretty sure I’m interrupting the datasheet incorrectly. Most importantly, the opamp gain at DC is around , so that additional 70 doesn’t really figure into the gain equations.

Beta is also dependent on Vce. Depending on the value of the sense resistor there is a chance that the opamp output might not be able to swing low enough to drive Q1 correctly. I want to ensure 4mA collector current regardless dstasheet my load.

It should not be used a design parameter for several reasons. I’d like to make a few comments: Dec 27, 1. The opamp and its negative lm3566n will lmm356n adjust Q1 base current such that the voltage across sense resistor R5 is identical to the voltage across R4. Dec 28, 8.

The second key to this circuit is that the transistor emitter current equals to the collector current. Dec 28, 4. You have several problems.
