ON Semiconductor STK672-600C-E Stepper Motor Driver
The STK672-600C-E from ON Semiconductor is a highly efficient, unipolar stepper motor driver IC that is designed to deliver precision and power in a compact package. This integrated circuit is part of ON Semiconductor's Motion Control product line, which is renowned for its reliability and performance in various motor driving applications.
This stepper motor driver is capable of driving a two-phase bipolar stepper motor with a supply voltage ranging from 10V to 44V. It is an excellent choice for applications requiring precise motor control such as in office automation machines, factory automation, and robotics.
The STK672-600C-E integrates a fixed off-time current regulator that operates in PWM mode, which can be used to drive the motor with a single clock pulse due to its built-in translator. This feature simplifies the control logic required, allowing for easy implementation into a wide range of designs.
Key features of the STK672-600C-E include:
- High-efficiency operation through a bipolar constant-current PWM drive
- Micro-stepping capability (up to 1/16 step) for smooth and precise motor movement
- On-chip voltage regulator for the internal circuit, which operates at 5V
- Thermal shutdown (TSD) and overcurrent shutdown (ISD) safety features
- High torque drive with an output current of up to 2A
The device is available in a compact, heat-dissipating package, making it suitable for applications where space is at a premium and thermal management is a concern. The inclusion of multiple protection features ensures that the STK672-600C-E not only delivers performance but also maintains a high level of safety and reliability, reducing the risk of damage due to overheating or overcurrent conditions.
Whether you are developing a new stepper motor application or looking to upgrade an existing design, the ON Semiconductor STK672-600C-E stepper motor driver provides a versatile and robust solution that can meet the demands of a wide array of stepper motor control scenarios.
