PublishTime： 2023-06-15 Article Source：NOVOSENSE News

NOVOSENSE has launched a new three-wire Hall-effect switch/latch NSM101x series to provide a high-precision solution for digital position detection, which can be widely used in the position detection of automotive actuators.

The NSM101x series three-wire Hall switch/Latch includes three models, namely, NSM1011 (unipolar Hall switch), NSM1012 (omnipolar Hall switch), and NSM1013 (Hall latch). Involving different switching points, working magnetic poles, output phase, normal power consumption and low power consumption modes, temperature compensation coefficient of magnet materials, packaging form, and other dimensions, the NSM101x series can fully cover different system requirements in various application scenarios. All models are automotive-qualified and industry-qualified. The automotive-qualified products meet the reliability requirements of AEC-Q100 Grade 0 and can work in the harsh environment of -40~150℃.

Wide operating voltage range and high-temperature stability

The NSM101x series achieves the industry-leading wide supply voltage range, with the absolute maximum ration of -20 ~ +40V and the operating voltage range of 2.7~ 38V. It is suitable for various application scenarios of LDO power supply and direct power supply by automotive low-voltage batteries.

Switching point temperature compensation coefficient for various magnet materials achieves a high degree of consistency of switching position in the full temperature range of -40~150℃ under the premise of customers using samarium cobalt, neodymium iron boron, ferrite, and other materials, improving the quality of the system.

Flexible selection

The NSM101x series has a variety of sensitivities for different magnetic sensing application scenarios, with switching points ranging from 15 to 100 gauss. For different target polar polarity, there are south and north pole models for selection; according to different output phase requirements, there are low output and high output models under the condition of B>Bop for selection; for different power consumption requirements, there are normal power consumption and low power consumption models for selection, with the average working current of the low power model as low as 8μA. High selection flexibility greatly meets the different customer requirements on different structural designs and systems.

Industry-leading reliability design

The NSM101x series Hall-effect switch/latch is AEC-Q100 grade 0 certified and is suitable for operating in high-temperature environments with junction temperature up to 175℃.

The product series supports over-current protection and over-temperature protection, and a long short circuit between the output and the power supply or ground wire will not cause product damage, which greatly improves the possibility of passing the complex onboard electrical performance test of the sensor module. In addition, the product line has industry-leading ESD performance, which is up to ±8kV with the HBM mode, improving robustness in component manufacturing and end-customer applications.

General package form for high compatibility

SOT23-3 package and TO92S package are compatible with mainstream competitive products in the industry and support through hole components welding, resistance welding, and PCB surface-mount technology so that the chip can be replaced directly under the premise that the structural design remains completely unchanged.
