Its wire coil is actuated by a smaller current from the ignition switch, at which time the iron core slams down to make contact and turn on the starter motor. Most non-Ford starter motors employ a solenoid built into the motor itself. This type of solenoid not only provides the motors electrical power but also mechanically engages the starters drive gear onto the flywheel.

Although this device uses an I2C interface with communication speeds up to 1 MHz, two of the eight pins are dedicated to Alert (pin3) and nReset (pin 6). The Alert pin is intended to be connected, if desired, to an interrupt pin on a microcontroller. According to section 3.5 (ALERT Pin) of the datasheet, "The output of the pin depends on the value of the temperature reading relative to programmable limits," and its function is "explained in a separate application note.

You can also see that I’ve made it very easy for heat to move away from the regulator (U1) and into the ambient environment or into other portions of the PCB. U1’s thermal tab is connected to a large copper pour, and this copper pour is shot through with vias that conduct heat down to the internal ground plane. If I were really worried about thermal issues I could also connect these vias to a copper pour on the bottom side of the board, but in this case, it would have been total overkill.

They are usually mounted on a circuit board like a servo motor with a gear box. They spin very fast and have to be geared down like a brushed dc motor. They are different than a brushed dc motor in that they are stronger, more efficient and last longer. They can be matched to a wider variety of propellers or loads by adjusting the gearing.

Dithering the stepper signal at a higher frequency than the motor can respond to will reduce this "static friction" effect. Because windings are better utilized, they are more powerful than a unipolar motor of the same weight. This is due to the physical space occupied by the windings.

They are not designed to spin continuously. Used to position print heads in ink jet printers, plotters, scanners. Travel at set speeds. Go to a spot and stop. When stopped and still turned on, will attempt to hold it is position. Forcing it to move in this position can damage the motor. Typically is controlled by a circuit board that counts shadows with an LED and light sensor or has a resistor that changes value depending upon position. Often zooms to one side when powered on to figure out where it is at.

Identical model motors vary, so each needs to be calibrated by banging against some edge ... think of the banging noise when an inkjet printer is turned on. Servo motors are good for robot wheels that have to turn a certain distance then stop. They are good for robots that have to balance themselves somehow. Auto pilots can use these to navigate a hallway. They are not good for spinning propellers like brushed dc motors and brushless motors.

The datasheet goes on to say that "the nRESET pin is internally connected to VDD with a pull up resistor of 50 kΩ." So... why are there two options for how to configure the nReset pin when it is not being used? Why not just recommend that it should be left floating (since it is already pulled high internally)? And, if there are indeed technical reasons for when the pin should be externally pulled up to VDD (for better noise immunity, as an example) then let us know what those technical reasons are.
