Introducing the L6228N Stepper Motor Driver from STMicroelectronics
The L6228N is a state-of-the-art integrated stepper motor driver from STMicroelectronics, designed to drive both windings of a bipolar stepper motor or bidirectionally control two DC motors. With its advanced features and robust design, the L6228N is an ideal solution for a wide range of applications that require precise motor control, including office automation, robotics, and industrial equipment.
This powerful driver chip integrates a dual DMOS full bridge with a high-voltage integrated circuit (IC) that can handle motor supply voltages up to 52V. The L6228N is capable of delivering an output current up to 2.8A, which can be adjusted through an external resistor. This allows for fine-tuning to match the specific requirements of your stepper motor, ensuring optimal performance and efficiency.
Key Features of the L6228N:
- Voltage and Current Capacity: Operating voltage range from 8V to 52V, with up to 2.8A output current capability.
- Integrated Protection: The device includes thermal shutdown, under-voltage lockout, non-dissipative overcurrent protection, and crossover-current protection, ensuring safe and reliable operation under various conditions.
- Control and Configuration: The L6228N offers programmable slow or mixed decay modes, along with a phase sequencer for easy motion control. PWM current control with non-dissipative current sensing is also provided for accurate motor torque regulation.
- Compact Design: Available in a PowerDIP24 (20+2+2) and SO24 wide-body packages, the L6228N is designed for space-constrained applications while still providing robust performance.
With its cross-conduction protection, the L6228N prevents simultaneous high-side and low-side conduction, which can lead to device failure. The chip's internal circuitry is optimized for low power dissipation, which, when coupled with its efficient power management features, makes it a highly energy-efficient solution for driving stepper motors.
Whether you're developing a new project or upgrading an existing system, the L6228N stepper motor driver from STMicroelectronics offers the performance, reliability, and advanced features necessary to meet your motor control needs.
