Power Tools
Leveraging the full-chain synergy of its IDM model, crmicro provides industrial-grade, efficient, and stable battery protection and motor drive solutions for power tool customers, helping customers develop high-performance and durable power tool products.
Solution Overview
Targeting the electronic control system for lithium-battery brushless power tools, the solution covers the full chain: AC-DC charging, battery protection, three-phase motor drive, and panel display. Integrating low-voltage SGT/Trench MOSFETs, low-current IGBTs, dedicated gate drivers, power management ICs and motor MCUs with low standby power design, it achieves precise motor speed regulation, optimizing overall energy efficiency and portable-use stability.
Solution Advantages
-
High-integration brushless motor drive: powerful output, low noise, maintenance-free operation, long life
-
Optimized power devices and battery management reduce no-load losses, and significantly improve runtime per charge and overall energy efficiency ratio
-
Multiple hardware & software safety protections (overload, overheat, reverse-connection, shock-resistant) ensure more reliable operation
-
MCU smart control algorithm supports precise multi-step torque adjustment
-
Fully self-developed technology ensures product consistency and extreme cost-effectiveness, supporting high-volume stable delivery to the market
