NOVOSENSE Launches NSM101x Hall-Effect Sensors for Automotive Position Detection

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.

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.
