NOVOSENSE has introduced the NSM101x series of three-wire Hall-effect switch and latch ICs, designed for high-precision digital position detection in automotive actuators and other demanding applications. The family includes unipolar, omnipolar, and latch variants, offering flexible configuration options for various system requirements.
NOVOSENSE NSM101x series Hall-effect sensors for vehicle position detection
Key Specifications
- Models: NSM1011 (unipolar switch), NSM1012 (omnipolar switch), NSM1013 (bipolar latch)
- Operating voltage: 2.7 V to 38 V (absolute max -20 V to +40 V)
- Temperature range: -40°C to +150°C (AEC-Q100 Grade 0)
- ESD protection: ±8 kV HBM
- Built-in protections: Overcurrent, overtemperature, output short-circuit withstand
- Packages: SOT23-3 and TO92S (compatible with mainstream products)
The devices support multiple switching points, output phases, normal and low-power modes, and temperature compensation for different magnet materials. They can be powered directly from low-voltage automotive batteries or through LDO regulators.
Target Applications
- Automotive actuators and position sensing
- Valve position detection
- Gear shift and pedal position
- Seat and mirror adjustment systems
- Industrial position sensing
The NSM101x series provides high reliability, excellent robustness against automotive electrical stresses, and easy drop-in replacement in existing designs thanks to compatible packages and pinouts.
