The AX101987 application field is incredibly vast - spanning everything from industrial robotics and vehicle motion control to telecommunications and medical applications. This product, designated as an electronic device, is designed to control the motor performance in microstepping applications by relying on current excitation. The high performance regulator works by setting a target current value for each excitation coil, then using a sample-and-hold architecture, the device pushes the actual coil current to match this target in a stepwise manner. Consequently, the motor rotates in equal microsteps on a cycle-by-cycle basis, providing an ultra smooth motion profile and highly accurate positioning.

The AX101987 works on the principle of pulsed current excitation. The controller will convert the desired device mode or motor speed setting into a target current for the excitation coils. The pulses are generated by the driver, in accordance with the target current profile, and are delivered to the motor through the power stage at constant time intervals. The current flow in the excitation coils is then sensed external to the device and converted into a voltage. This voltage is then sampled and compared to the target current profile and the results are used to adjust the pulses in order to maintain the desired motor speed.

The AX101987 operates in an ultra-low power mode, drawing only 0,44A from the power supply while running at a standard speed. The device also has very low noise, with negligible glitching, even at the highest motor speed settings. The robust power stage integrated into the device offers high efficiency, low thermal design and low power consumption for consistently smooth and steady performance.

The AX101987 boasts a broad range of features, such as over-temperature protection and speed limit setting, as well as enhanced user flexibility when it comes to powering multiple motor applications. The product is also equipped with a range of built-in self-calibration modules, enabling users to quickly and accurately configure and adjust parameters of the device to suit their unique application requirements.

In addition, the AX101987 is capable of operating in multiple control modes, such as speed, open loop or pulse/dir. This provides users with even more control and flexibility of their motor applications and allows them to get the most out of their system performance. The device also works well with both brushed and brushless motors, allowing for a wide variety of applications.

The AX101987 is a powerful and integrated motor driver solution that provides a high degree of flexibility, accuracy, and control. Its several features make it an ideal choice for a wide variety of industrial, robotic, automotive, telecommunications, and medical applications as well as for a variety of other end-user needs.
