So what is an ESC? Well, electronic speed controllers are used to control brushless motors, in thisc ase the motor has a triple phase input. To control this input, the ESC must apply a special sequence of LOWs and HIGHs signals in a predefined order. It has to conmutate very fast and by taht rotate the rotor of the motor. In this tutorial we will see how to control the rotation, the speed, detect the BEMF and by that know when to make the switch to the next step of the sequence. So this is a sensorless brushless motor speed controller since it uses no sensor to detect the rotor position. We will learn: - The schematic and why we need each part - Triple phase MOSFET bridge control - BEMF detection and 0 cross - Interrumprions and internal comparator of ATMEGA328 - PWM control

The Alpha & Omega Semiconductor AO3422 is a high-performance, N-channel enhancement mode field effect transistor (FET) designed using advanced trench technology. This technology ensures the component offers low RDS(ON) and minimal gate charge, making it highly efficient for use in various electronic applications. Key features of the AO3422 include a 55V drain-source voltage (VDS), a continuous drain current (ID) of 2.1A at a gate-source voltage (VGS) of 4.5V, and RDS(ON) values as low as 160mΩ at VGS = 4.5V. It supports a wide gate drive range from 2.5V to 12V, making it versatile for different operating conditions. Specifically designed for load switch applications, the AO3422 comes in a compact SOT23 package, offering a blend of performance, efficiency, and space-saving design. Its absolute maximum ratings include a drain-source voltage of up to 55V, gate-source voltage of up to +12V, and a power dissipation of 1.25W at 25°C. With thermal characteristics designed for robust operation, including a maximum junction-to-ambient thermal resistance of 75°C/W for short durations, the AO3422 is optimized for high-performance switch operations in a range of electronic circuits.
