NOVOSENSE launches automotive- and industrial-grade NSCSA240-Q series current sense amplifiers to address PWM transient interference challenges

　　NOVOSENSE announced the launch of its new bidirectional current sense amplifier series, NSCSA240-Q, covering both industrial and automotive versions, designed for high-voltage PWM systems in vehicles and industrial equipments. The NSCSA240-Q series integrates enhanced PWM rejection technology, supporting bidirectional current sensing with exceptional transient immunity, automotive-grade precision, and flexible configurability. Featuring an ultra-wide input common-mode range from –4V to 80V, a typical input offset voltage of ±5μV, and a 135dB DC Common-Mode Rejection Ratio (CMRR). This series effectively tackles the challenge of high-frequency transient interference in PWM systems, providing a highly reliable current monitoring solution for automotive electronic power steering (EPS), motor drive, industrial automation and other applications. The NSCSA240-Q series meets the AEC-Q100 automotive reliability standard.　　Superior Transient Immunity: Reliable Performance in High-Voltage PWM Environments　　In PWM systems, rapid switching can cause severe common-mode voltage fluctuations that distort output signals in conventional amplifiers. The NSCSA240-Q series achieves an AC CMRR of 90dB at 50kHz, effectively suppressing ΔV/Δt transients. Its proprietary transient suppression design reduces output disturbances by up to 80%, achieving a recovery time of less than 10μs under 80V common-mode voltage transients. With a bandwidth ranging from 450kHz to 600kHz (gain-dependent), it supports both high-speed overcurrent protection and accurate low-frequency PWM signal capture—ensuring stable, low-noise signal performance for EPS, motor drive and industrial motor control systems. The wide –4V to 80V input common-mode range offers broad dynamic capability and robust tolerance across 12V, 24V, and 48V vehicle power architectures. Furthermore, ±2000V ESD protection (HBM/CDM) enhances resistance to external electrical disturbances, ensuring overall system reliability.NSCSA240-Q Series Application Diagram　　Automotive-Grade Precision: ±5μV Offset and ±0.1% Accuracy Across –40°C to 125°C　　Designed to meet the increasingly stringent current measurement requirements of automotive electronics, the NSCSA240-Q series delivers exceptional measurement stability. It features a typical input offset voltage of only ±5μV (maximum ±25μV) and achieves ±0.1% accuracy over a wide temperature range (–40°C to 125°C). With a typical gain error of 0.05%, it ensures reliable and consistent current monitoring even under harsh conditions. Fully qualified to the AEC-Q100 automotive standard, the series guarantees long-term reliability in demanding in-vehicle environments.　　Flexible Integration: Multiple Gain and Package Options for Design Optimization　　As automotive systems trend toward miniaturization and integration, the NSCSA240-Q series is engineered for flexible and space-efficient design. It offers four fixed gain options—20V/V, 50V/V, 100V/V, and 200V/V—supporting shunt resistors ranging from 10mΩ to 0.1mΩ for flexible current detection. The series is available in two compact packages: SOIC-8 (4.9mm × 3.91mm) and TSSOP-8 (3mm × 4.4mm), allowing easy integration into space-constrained motor controller PCBs and helping designers optimize system layouts within limited board area.NSCSA240-Q Series Package

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.

Murata Launches World’s First 10µF/50Vdc MLCC in 0805-inch Size for Automotive Applications

　　Murata Manufacturing Co., Ltd. has announced the new GCM21BE71H106KE02 multilayer ceramic capacitor (MLCC) has entered mass production. The device is the world's first 0805-inch size (2.0 x 1.25 mm) MLCC to offer a capacitance of 10µF with a 50Vdc rating and is specifically engineered for automotive applications*. This cutting-edge product marks a significant advancement in MLCC design, delivering a smaller 0805-inch package while maintaining capacitance, voltage rating, and MLCC reliability.　　Advancements in advanced driver-assistance systems (ADAS) and autonomous driving (AD) technologies necessitate deploying an increased number of integrated circuits (ICs) within vehicle systems. This surge in ICs simultaneously leads to a greater demand for supporting high-capacitance passive components while imposing tighter spatial constraints – as a greater number of capacitors must be accommodated on increasingly crowded automotive printed circuit boards (PCBs).　　Designed for 12V automotive power lines, the GCM21BE71H106KE02 capacitor leverages Murata’s proprietary ceramic material and thinning technologies to help engineers to save PCB space and reduce the overall capacitor count, resulting in smaller, more efficient, and reliable automotive systems. As the first automotive-specific MLCC to achieve a 10µF capacitance with a 50Vdc rating in the compact 0805-inch size the GCM21BE71H106KE02 represents a significant advancement in capacitance efficiency. It offers roughly 2.1 times the capacitance of Murata’s previous 4.7µF/50Vdc product, despite sharing the same physical size. Furthermore, compared to the previous 10µF/50Vdc MLCC in the larger 1206-inch size (3.2 x 1.6 mm), the new MLCC occupies approximately 53% less space, providing substantial space savings for automotive applications.　　Murata will continue to pursue further miniaturization and increased capacitance of MLCCs, while expanding its product lineup to meet the evolving needs of the automotive market. These efforts will support the industry as they look to develop higher-performance and more multifunctional vehicles. In addition, by downsizing electronic components, Murata aims to reduce material usage and improve production efficiency per unit, helping to lower electricity consumption at its manufacturing sites and reduce overall environmental impact.
