Part Number: LM51770 Other Parts Discussed in Thread: LM5176 Tool/software: Hi, this device is described as bidirectional so I was wondering if this device could be used as one half of a bridge that could be used for bidirectional motor or Peltier control…
HI Jeff,
Could you please attach the filled out LM51770 Quickstart-Calculator to this thread? This would be the most efficient workflow for us to do a schematic review.
Note: I recommend to use the newer version LM51770 (which is pin compatible)
Best regards…
Hi Jose,
Webench is more strict and tries to gives you out of the box solution.
While the Excel tool gives you much more freedom where you can
- judge the cooling capabilities,
- use MOSFETs in parallel
- define load profiles and decide which is more…
Hi Jareth,
LM5176 and the LM34936 are sharing the same control logic. - you may have check against this one only
The LM51770 and LM51772 are completely different and newer designs.
As mentioned also have better support on reverse operation and average…
Hi Tsung-Hui-Chen,
I would recommend to start the design with the newer version of this device: LM51770 (identical footprint and features but better performance, e.g. input and output voltage range)
The Simplis Model is only shared under NDA. Please contact…
Hello Stefan, In a private message, I sent you the LM51770 design calculator tool that I customized for my application. Please review it and let me know if it is okay to proceed with it.
