These capacitors will also act to slow the circuit down. It can also be due to cheap op-amps bsx138 the LM that cannot swing their output all the way to the Vcc rail. However, as SpehroPefhany points out, this is not the full story.

The BSS is particularly suited for low voltage, low current applications such as small servo motor control, power MOSFET gate drivers, and other switching applications. Licensee agrees that bs1s38 has received a copy of the Content, including Software i.

My crystal ball is a bit cloudy this afternoon. Licensee agrees that it shall comply fully with all relevant and applicable export laws and regulations of the United States or foreign governments “Export Laws” to ensure that neither the Content, nor any direct product thereof is: You may be able to get 1MHz from the transistor you want to use if you don’t mind very rounded edges.

Once the MOSFET turns on, the output voltage will then drop towards zero as the current through R3 flows through the channel rather than the body diode. The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering The restricted substances and maximum allowed concentrations in the homogenous material are, by weight: When the input is pulled low, the source will be at 0V, but the gate will remain at 3.

I’ve added a bit on how the circuit works. You can simulate it or build it and test it. I want to use a BSS N-mosfet transistor which is mainly used in logic level shifting.

Upon reasonable advance written notice, ON Semiconductor shall have the right no more frequently than once in any 12 month period during the term of the Agreement, through an independent third party approved by Licensee in writing such approval not to be unreasonably withheldto examine and audit such records and Licensee’s compliance with the terms of Section 2.

Here are the data sheet suggestions: The BSS needs about 2. And lastly the the supply to the op-amp may be too low to achieve the needed gate drive voltage. Spehro Pefhany k 4 The following Sections of this Agreement shall survive the termination or expiration of this Agreement for any reason: I added the G-S capacitance 27pF to the G-D capacitance 13pF, since they’re both ‘almost’ AC grounded on the other side the G-D capacitance less so, hence my Miller comment- but even if it doubles the effective capacitance you’re still well under pF.

The capacitance has the biggest impact in down-shifting on both rising and falling edges. In simulation it worked just great but i wanted to get a second opinion. Licensee is and shall be solely responsible and liable for any Modifications and for any Licensee Products, and for testing the Software, Modifications and Licensee Products, and for testing and implementation of the functionality of the Software and Modifications with the Licensee Products.

If you don’t care at all about speed it will work. Contact Local Sales Office. Speed is already pretty terrible because of the 10K pullup and other capacitance. Lefteris 1 Figure 30 indicates the op-amp with virtually no resistive load can handle pF without going unstable, so you’re okay, but not a lot of margin.

The channel resistance essentially acts as a potential divider with R4 or R3 when the output is pulled low. Junaid I’ve gotten 4MHz out of this type of level shifter before by using 2.


The LMV output, even with a 10K load to 2. The higher the capacitance, the slower the circuit. Your request has been submitted for approval.

As such it will be pulled up to 3. Post Your Answer Discard By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policybsx138 that your continued use of the website is subject to these policies.

You need 20mA 1V across 50 ohms so refer to Figure 5 and adjust for possible unit to unit bss38 and add some safety factor. Any provision of this Agreement which is held to be invalid or unenforceable by a court in any jurisdiction shall, as to such jurisdiction, be severed from this Agreement and ineffective to the extent of such invalidity or unenforceability without invalidating the remaining portions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

Yes, it will work fine. There are some limitations to consider when trying to do this however.
