NTMicroDrive

NTMicroDrive, an ASIL A ready software stack that permits the direct control of brush-type (DC), stepper, or brushless motors (BLDC) with the use of Micronas HVC 4223F. NTMicroDrive is a production-ready and highly flexible, customizable firmware with sophisticated communications, monitoring and power management functions as well as a configuration software tool. The software stack allows complex motor control algorithms such as Space Vector Modulation (SVM) for permanent magnet synchronous motors (PMSM), six-step commutation with sensor feedback or without sensor control, as well as various stepper configurations.

Customer benefits

• Certification ready for ISO 26262 ASIL A – Automotive SPICE Level 1 (up to 2)
• Short time to market
• Ready to use Software (Out of the box)
• Usable for the different types of motors, only with parameter change
• Only 50% needed for NTMicroDrive functionality, 50% free for Customer Application
• MISRA Compliant
• PCLint tested

Typical applications

Automotive

• Headlight height adjustment
• Electric window lift
• Electric seat adjuster
• Electric mirror adjustment

Industrial

• Safety interlock
• Feeder system

The NTMicroDrive Enterprise-Board is a development and production ready platform that permits the direct control of brush-type, stepper or brushless motors (up to 25 watt). The motor control is empowered by the TDK Micronas HVC 4223F Motor Controller. Next to the motor driver part is an USB/LIN-Adapter for rapid prototyping. Both parts can be separated and used independently.
For commercial applications the NTMicroDrive Software Stack together with the HVC 4223F Motor controller provides a ready-to-use solution.
