The A4975SLBTR-T full bridge PWM microstep driver is a motor/motion/ignition controller and driver manufactured by Allegro. This integrated circuit is designed to allow microstep motor control with excellent torque and low noise performance across a wide range of operating conditions. Its on-board microstepping capability helps to maintain motor torque over a large range of speed settings, while its low on resistance DMOS output drivers provide a high level of efficiency and low thermal dissipation. The A4975SLBTR-T is fully programmable, allowing the user to configure the driver to suit their specific application, such as microstepping resolution, microstepping frequency, and step time. Additionally, it features over-temperature, over-current, and under-voltage protection to ensure the longevity of the device.
