UTP6A35BL

The UT6A35BL is a unipolar stepper motor driver. It is designed to control two-phase hybrid stepper motors and works well for small and micro stepper motors. This driver board is based on a leadshine hybrid stepping drive. It supports a pulse response frequency of up to 200 KHz, which is higher than any other type of stepping drive. It also offers low-voltage protection, auto-stop protection, over-voltage and over-current protection, short-circuit protection, and over-temperature protection. The integrated thermal protector serves as a protective measure against catastrophic damages in the event of over-temperature.

The UT6A35BL is comprised of two bridges, one for each phase, which comprises of two high-side and two low-side MOSFETs. To control the motor, the UT6A35BL receives digital pulses from a microcontroller. The bridge is then turned on or off according to the polarity of the pulse.

The application fields of the UT6A35BL are mostly linked to industries that require precision movements, such as various assemblies and machinations. It can be used in applications like engraving, 3D printing, robotics, industrial automation, medical equipment, gaming machines, and many other types of motion control systems. Additionally, this driver board is well suitable for use in electric scooters and bikes, motor drive controllers, and various DIY projects.

The working principle of the UT6A35BL is based on the Half-Step Sequence method, which is common for stepper motor drivers. This sequence will step the motor from one angular position to the next. It involves alternating switches of the two power bridges in the driver, which results in a digital pulse that controls the angular displacement of the motor. This sequence is known as the Two-Phase Bipolar Drive Sequence.

The half-step sequence of the UT6A35BL is determined by the length of the digital pulse sent by the microcontroller. The longer the duration of the pulse, the higher the step angle will be. The shorter the duration, the smaller the step angle will be. This way, the user can accurately and precisely control the stepper motor without relying on an external controller.

In addition to the half-step sequence, the UT6A35BL also supports other types of pulses, such as microstepping, which uses smaller step angles for smoother motion. With microstepping, the user can achieve precise motions, even when there is a lot of torque or inertia in the system. As a result, the UT6A35BL is an ideal choice for applications that require accurate and precise movements.

To sum up, the UT6A35BL is a versatile and reliable driver board designed to control stepper motors. It is suitable for use in various types of industries and applications, such as manufacturing, automation, robotics, medical equipment, and 3D printing. It offers a range of features, such as pulse response frequency up to 200 KHz, low-voltage protection, auto-stop protection, over-voltage and over-current protection, short-circuit protection, and over-temperature protection. It also supports multiple types of sequences, such as the Half Step and Microstepping Sequences, to achieve accurate and precise motions.
