Industry & Robotics
Current sensing, position feedback and speed measurement for servo drives, robot joints, industrial inverters and automation equipment, meeting industrial-grade reliability and wide-temperature requirements.
Industry & Robotics
Building on its automotive-grade design capability and process platform, RJMICRO devices also suit industrial electronics, offering a localized option where even higher reliability and wider temperature ranges are required.
Industrial applications share the traits of continuous operation and high maintenance cost, so long-term stability and interference immunity matter more. In servo and variable-frequency drive phase-current loops, linear Hall current sensors sample current directly without an isolated supply.
Systems and scenarios covered
Industrial automation
- Servo drives and variable-frequency drives: three-phase current sensing
- robot joints and harmonic reducers: angle and position feedback
- CNC machine tools and textile machinery: spindle speed and position sensing
- instruments and flow meters
Motors and actuators
- Three-phase brushless motor commutation
- power tools
- proximity detection and limit switches

Automotive-grade Vertical / Planar Hall Latch
3.3 V–24 V wide supply, 40 V load-dump and reverse-polarity protection, symmetric switching points producing a near-50% duty square wave — an ideal choice for motor commutation.
TMR 3D Position / Angle Sensor
TMR tunnel-magnetoresistance analog output with highly sensitive 3D magnetic field detection for angle and position measurement. Pin-to-pin compatible with TDK TAS2143.
IMC / 3D Hall Position Sensor
IMC integrated magnetic concentrator plus vertical Hall technology, heterogeneously integrated for high-sensitivity measurement with on-chip algorithms delivering high-accuracy angle output.
150 mA, 40 V Ultra-low Quiescent Current Automotive LDO
3 V–40 V wide input with fixed 3.3 V / 5 V output, 5.5 µA typical quiescent current and 800 nA shutdown current — ideal for always-on systems connected directly to the battery.
150 / 300 / 450 mA, 60 V Ultra-low Quiescent Current Automotive LDO
3 V–60 V wide input with up to 45 V transient tolerance; fixed 1.8/2.5/3.3/5 V and adjustable 1.8 V–15 V outputs covering the current range of 12 V / 48 V systems.
