Motor Drivers, Controllers, and the MIC502YNThe MIC502YN is a hybrid IC that was developed by Micrel Inc. It is a high-performance, low-voltage, low power, and low voltage compatible single-noise filterable three-phase motor control and bridge driver IC. The device is a speed and torque controller designed to meet the requirements of a variety of applications, including brushless DC motors, three-phase AC motors, stepper motors, and industrial robot controllers. It has a wide input voltage range of 4.75V to 36V and can operate in both a single-ended and push-pull operating mode. The MIC502YN combines a double-pole motor drive, low-voltage circuit, current loop control, and low-voltage detection circuitry to provide stable, low-noise, high-performance motor speed and torque control. It is capable of controlling motors up to 3.2 W and up to 30 amps of continuous current with the proper external pullup and pulldown logic. It includes a user programmable MOSFET gate driver that allows for operation in either low-side or high-side PWM control modes. The IC also includes control for motor phase current-mode driving, phase-out delay control, common mode voltage control, and dead band programming. The IC has built-in current limiting, over-current and thermal protection, which ensures safe operation and prevents damage to the motors. The device also includes an integrated differential line receiver circuit, which detects EMC and other signal disturbances on the power line and filters them before they reach the motor drive. The MIC502YN also includes a voltage regulator that helps to maintain the required voltage levels for the motors. The MIC502YN is ideal for applications where high motor speed and torque control accuracy is required. It can also be used in applications that require low voltage and high-noise immunity, such as electric and hybrid vehicles, factory automation systems, medical equipment, industrial robotics, unmanned aerial vehicles, and commercial robotics. The MIC502YN provides excellent control of the motor speed and torque via a range of options. It has a wide operating temperature range of -40°C to +125°C, an internal over-voltage protection of 9V, and an over-temperature protection of 150°C. It is also RoHS compliant and can be purchased in several different packages. Overall, the MIC502YN is an ideal solution for providing effective and reliable motor speed and torque control. It is capable of controlling motors up to 3.2W and up to 30 amps of continuous current with the proper external pullup and pulldown logic. It includes built-in features such as over-current and thermal protection, and differential line receiver circuits that help provide stability and noise immunity. It is also RoHS compliant, making it suitable for a variety of industrial applications.
