L6202 - Dual Full Bridge Motor Driver Integrated Circuit

The L6202 is a dual full-bridge motor driver integrated circuit (IC) designed for driving bipolar stepper motors and bidirectional DC motors. It #39;s manufactured by STMicroelectronics and is commonly used in various motor control applications. Here are some key features and characteristics of the L6202: Dual Full-Bridge Configuration: The L6202 contains two independent full-bridge driver circuits, allowing it to control two separate motors or motor coils. Motor Types: It #39;s designed to drive bipolar stepper motors and bidirectional DC motors, making it suitable for a wide range of motor control applications. Current Sensing: The IC often includes current sensing features that allow you to monitor the current flowing through the motor coils for protection and feedback purposes. H-Bridge Configuration: Each full-bridge driver is essentially an H-bridge configuration, which provides bidirectional control of the motor #39;s rotation. Built-in Protection: The L6202 typically incorporates protection features such as overcurrent protection, thermal shutdown, and voltage clamping to ensure safe operation and prevent damage to the IC. Logic Inputs: The IC can be controlled using logic-level inputs, allowing it to interface with microcontrollers and digital control systems. PWM Control: It #39;s common to use pulse-width modulation (PWM) signals to control the speed of the motors connected to the L6202. Internal Freewheeling Diodes: The internal diodes help to protect the IC and the connected power supply by providing a path for the motor #39;s back-EMF during switching. The L6202 is frequently used in applications such as robotics, CNC machines, 3D printers, industrial automation, and automotive systems where precise motor control is required. It provides a convenient solution for driving motors with various control features and protection mechanisms.
