Stepper motors offer unique advantages over direct current (DC) and brushless DC (BLDC) motors in many applications. A bipolar stepper provides accurate open-loop position as well as zero-speed torque without using a control loop or external sensors.
AN296190 - The data contained within this application note allows the user to effectively choose an Allegro current sensor package based on their system’s specifications.
AN296216 - This application note describes how to calculate the maximum power MOSFET switching frequency in BLDC motor gate drives.
This application note describes the operation of the bootstrap circuit and guidelines in selecting a bootstrap capacitance value to ensure normal operation of the gate drives.
Brochure
Achieve all of your design goals for voltage and power levels with a single-platform architecture by combining Allegro drivers, sensors, and regulators.
This application note outlines common techniques and challenges in the employment of a single half-bridge driver configuration to control current in a simple two-terminal inductive load.
Whitepaper
This paper will focus on the basics of the sensorless control algorithm, the advantages of different sensing techniques, and how the GUI can drive a full-featured sensorless sinusoidal BLDC motor with no software programming required.
