Hall-effect sensor chips support position detection, wide voltage operation, protection features, and automotive applications.
NOVOSENSE has launched the NSM101x series of three-wire Hall-effect switch and latch ICs, designed to provide high-precision digital position detection for automotive actuators and other position sensing applications.
The NSM101x family consists of three models: NSM1011, a unipolar Hall switch; NSM1012, an omnipolar Hall switch; and NSM1013, a Hall latch. The series offers different switching points, working magnetic poles, output phases, normal and low-power operating modes, temperature compensation coefficients for different magnet materials, and multiple package options. These variations allow the devices to meet different system requirements across a wide range of applications. The series is available in both automotive-qualified and industry-qualified versions. The automotive-qualified models meet AEC-Q100 Grade 0 reliability requirements and are designed to operate in temperatures ranging from -40°C to 150°C.
The series features a wide supply voltage range, with an absolute maximum rating of -20V to +40V and an operating voltage range of 2.7V to 38V. This enables the devices to support both LDO-powered systems and direct power supply from automotive low-voltage batteries.
The devices also integrate overcurrent protection and overtemperature protection. They are designed to withstand prolonged short circuits between the output and the power supply or ground without damage, improving the likelihood of passing demanding automotive electrical performance tests for sensor modules. In addition, the series provides ±8kV Human Body Model (HBM) ESD protection, helping improve robustness during component manufacturing and in end-use applications.
The series is offered in SOT23-3 and TO92S packages, which are compatible with mainstream competing products. The devices support through-hole soldering, resistance welding, and PCB surface-mount technology, enabling direct replacement in existing designs without requiring changes to the mechanical or structural layout.
