Selecting the right motor driver depends on your motor type, voltage, current, and control requirements. For BLDC motors, consider the ANB8xxx series with integrated gate drivers and protection features. For stepper motors, the ANSxxxx series provides microstepping capability and smooth motion control. Key parameters to consider include: supply voltage range, peak output current, PWM frequency capability, protection features (overcurrent, thermal, undervoltage), and control interface (PWM, SPI, or analog). Our Motor Driver Selection Guide provides detailed parameter comparisons and application recommendations.

Review our Motor Driver Selection Guide or contact our FAE team with your motor specifications for personalized driver recommendations.

AnalogySemi gate drivers feature high-voltage capability up to 600V, excellent noise immunity with high CMTI (Common Mode Transient Immunity), fast switching speeds for high-frequency applications, and comprehensive protection features including undervoltage lockout (UVLO), overcurrent protection, and thermal shutdown. The ANGxxxx series offers single and dual-channel configurations with various input logic options (TTL, CMOS, differential). These drivers are ideal for motor drives, power supplies, inverters, and DC-DC converters requiring reliable high-side and low-side MOSFET/IGBT driving.

Contact our FAE team for gate driver selection based on your switching frequency, voltage, and isolation requirements.

Troubleshooting motor drive noise requires systematic investigation. First, identify the noise source - check if it's conducted (on power lines) or radiated (EMI). For conducted noise, add input filtering with common-mode chokes and capacitors. For radiated noise, minimize loop areas in high-current paths and use shielded cables. Check grounding topology using a star ground configuration. Verify decoupling capacitors are placed close to power pins. Ensure gate drive signals are clean without ringing. Our Motor Control Design Guide and PCB Layout Best Practices articles provide detailed troubleshooting procedures.

Follow the systematic troubleshooting guide in our technical articles or contact our FAE team for assistance with specific noise issues.

AnalogySemi offers a comprehensive range of power management ICs including DC-DC converters like the ANP34063 buck/boost controller for efficient power conversion, and low-dropout linear regulators like the ANL7805 for noise-sensitive analog circuits. Our power management portfolio covers applications from battery-powered devices to industrial power supplies. Each product is designed with features like thermal protection, current limiting, and enable control for robust system operation.
