NCV70517MW002R2G 1.5A motor driver IC
The NCV70517MW002R2G is a high-performance stepper motor driver from ON Semiconductor, designed for precise motion control in automotive and industrial applications. This advanced IC integrates a dual full-bridge MOSFET driver capable of delivering up to 1.5A per phase, supporting microstepping resolutions up to 1/16th step for ultra-smooth motor operation. The device operates from a wide 5V to 45V supply range, making it suitable for 12V and 24V automotive systems as well as industrial automation equipment. Its SPI-compatible serial interface enables precise control of current regulation, step mode, and decay modes, while the integrated current sensing eliminates the need for external sense resistors, reducing component count and PCB space. The NCV70517MW002R2G features adaptive decay mode switching that automatically optimizes torque ripple and power efficiency across different speed ranges, particularly beneficial for fuel injection systems, HVAC actuators, and robotic positioning mechanisms.
This motor driver incorporates comprehensive protection circuits including thermal shutdown, overcurrent protection, and undervoltage lockout (UVLO), ensuring reliable operation in harsh environments. The device's low RDS(on) MOSFETs (0.5Ω typical) minimize power dissipation, while its PWM current control maintains consistent torque output. Packaged in a 24-pin SOIC (300mil) with exposed thermal pad, the NCV70517MW002R2G achieves excellent thermal performance and operates across the automotive temperature range (-40°C to +150°C junction temperature).
