Supporting up to 1500W motor drive, NSUC1602 from NOVOSENSE easily addresses high current challenges

　　NOVOSENSE announced the launch of NSUC1602, a high-integration embedded motor control IC, following its introduction of NSUC1610, a small motor driver SoC for automotive applications in early 2023. Compared to the single-chip NSUC1610 that integrates LIN and MOS power stages, NSUC1602 as a SoC, supports an external independent power MOSFET design. This innovative approach enables it to effortlessly address applications requiring higher current.

　　In addition, NSUC1602 integrates three half-bridge pre-drivers, expanding the motor control power range to 20W-1,500W. This enhancement not only further optimizes the control performance of BLDC motors, but also better meets the requirements of applications with higher power output. In the realm of xEV, thermal management systems are particularly complex and crucial for ensuring overall vehicle performance. These systems are responsible for managing the temperatures of electric motors, power electronics, and battery, while ensuring optimal comfort for passengers in the cabin. An efficient thermal management system not only helps extend battery life, but also prevents the risks of thermal runaway caused by overheat, thereby safeguarding safe operation of xEVs.

　　In the realm of xEV, thermal management systems are particularly complex and crucial for ensuring overall vehicle performance. These systems are responsible for managing the temperatures of electric motors, power electronics, and battery, while ensuring optimal comfort for passengers in the cabin. An efficient thermal management system not only helps extend battery life, but also prevents the risks of thermal runaway caused by overheat, thereby safeguarding safe operation of xEVs.

　　To achieve these objectives, thermal management systems rely heavily on precise control of various actuators, such as electric compressor, electronic water pump, oil pump, fan motors, valves, and HVAC control modules. The motors driving these actuators typically need high power output to ensure stable and precise performance under a wide range of operating conditions, thereby meeting the strict requirements of efficient and accurate control for xEV thermal management systems.

　　NSUC1602, a highly integrated embedded motor control IC from NOVOSENSE, plays a pivotal role in managing key actuators in xEVs with its exceptional integration features and powerful motor control algorithms. This IC integrates an ARM® Cortex®-M3 core and efficient three-phase pre-driver circuits, and supports more advanced and complex motor control algorithms, such as FOC sensored or sensorless vector control. These advanced algorithms significantly enhance the precision and efficiency of temperature management for motors and electronic devices, providing robust technical support for intelligent three-phase brushless DC motor control applications, including automotive electronic cooling fans and electronic water pumps. Additionally, NSUC1602 incorporates a series of optimization designs to significantly improve overall system efficiency, ensuring stable performance under high-load operating conditions.

　　NSUC1602 meets the reliability requirements of AEC-Q100 Grade 0, and operates stably at extreme temperatures (up to 175°C wafer junction temperature). This SoC comes with further enhanced built-in diagnostics and protection functions that ensure high system reliability and comprehensive security protection for users.

　　While maintaining a highly integrated design, NSUC1602 also has an optimized power management solution. The LIN port supports ±40V reverse voltage protection, and the BVDD pin supports a withstand voltage range from -0.3V to 40V, allowing direct power supply from a 12V automotive battery. This helps simplify system design and notably reduce development costs.

　　NSUC1602 demonstrates extensive applicability for diverse applications. With superior motor control performance, NSUC1602 can play a crucial role in a wide range of BLDC and BDC applications requiring precise temperature control and efficient power transmission, such as automotive electronic water pumps, cooling fans, air conditioning blowers, seat adjustment, sunroof control, or tailgate control. Its optimized power management solution ensures that these devices achieve significant energy consumption reduction and substantial service life extension, while providing exceptional performance.
