No time to do design analysis? It is not a problem anymore. Electronics Believer created a design template for NMOS lowside relay driver. All you need to do are to fill in the input data and let the template do the math.
This is a great tool to speed up component selections, design and analysis. Thus, shorten development time.
How this Design Template for NMOS Lowside Relay Driver Works
Model Circuit
The Template
The template is made in excel thus everybody can use it. All the fields in orange are inputs. Which means the user should provide values on it. On the other hand, all the fields in green are computation results with the formula. These must not be altered. Otherwise, the template will result to error.
