Adapting to challenging magnetic environments: MT73xx 3D dual-output Hall latches from NOVOSENSE enable precise automotive motor control

　　The NOVOSENSE MT73xx series dual-output Hall latches, based on 3D Hall technology, support SS (Speed & Speed) or SD (Speed & Direction) dual-channel outputs and complies with Automotive Grade 0 standards. Ideal for motor control systems such as power windows, liftgates, and sunroofs, this product family enhances the accuracy and stability of speed and position detection, optimizing overall in-vehicle comfort.　　In motor control systems, precise detection of speed and direction signals directly influences system response speed and operational stability. Traditional solutions typically rely on a combination of two separate Hall latches, requiring high magnetic ring installation precision. This often leads to issues such as signal phase deviation, poor synchronization, and structural complexity.　　Integrates a 3D Hall sensing structure with inherent orthogonal output characteristics, the MT73xx series can simultaneously deliver dual-channel speed signals (SS output) with a 90° phase difference or speed and direction signals (SD output), making it widely suitable for “speed-direction” detection applications. This design reduces dependency on precise positioning of magnetic poles, mitigates dual-channel phase deviation, simplifies system architecture, and improves overall system stability, providing a more flexible and reliable solution for motion control detection.　　Compatibility with diverse magnetic ring configurations enabled by VHS technology　　To achieve high-precision 3D sensing, the MT73xx series adopts NOVOSENSE’s proprietary VHS (Vertical Hall Sensor) technology. Through combinations of XY, YZ, and XZ axial sensing, any two axes naturally deliver orthogonal outputs, enhancing signal synchronization.　　Additionally, the MT73xx series offers excellent compatibility with various magnetic ring configurations – whether axial, radial, or irregularly shaped magnets – maintaining robust duty cycle performance. This allows customers to adapt designs flexibly depending on magnetic ring characteristics and installation environments, further reducing development complexity and tuning costs.　　Dual-output design for optimized system integration　　Regarding system integration, the MT73xx’s dual-output capability allows it to replace traditional single- or dual-Hall solutions by directly transmitting SS (Speed & Speed) or SD (Speed & Direction) signals to ECU, minimizing the requirements for peripheral redundant position sensors.　　This approach not only saves PCB space and simplifies structural layouts, but also enhances solution integration, offering greater design flexibility for innovative applications in motor control and intelligent cockpit systems.
