LMD18200T 3A 55V H-Bridge Motion Control TO-220-11 (LMD18200T TO-220-11) The LMD18200T is an advanced monolithic H-Bridge designed for high-current motion control applications. It utilizes a multi-technology process (BCS) which combines bipolar and CMOS control circuitry with DMOS power devices on the same monolithic structure. This design allows the LMD18200T to drive DC motors, stepper motors, and solenoids with exceptional efficiency. It is capable of delivering up to 3A of continuous output current and can handle peak currents up to 6A, making it one of the most robust integrated motor drivers available.
This IC is primarily used in robotics, factory automation, and CNC machines. It is a premium-grade component for Arduino electronics projects in India that require high-power motor control with integrated safety features, such as current sensing and thermal warning, providing a professional-grade solution for heavy-duty DIY automation and electric vehicle prototypes.
