Products
Three product lines cover smart sensors, smart motor control SOCs and automotive power/driver devices — a complete sensing and control architecture qualified to AEC-Q100 Grade 0. Every device is labelled production, sampling, design or concept so you can judge the right time to design it in.
RJSENSE · Smart Sensors
Current sensing, position and angle, speed measurement and Hall switches — built to meet the accuracy, bandwidth and temperature demands of automotive powertrain and chassis systems.
Automotive-grade Linear Hall Current Sensor
Programmable sensitivity from 0.5 mV/G to 11.5 mV/G, 240 kHz bandwidth, 2.2 µs response and ±1% sensitivity error over the full temperature range — built for three-phase traction inverter current sensing.
Differential Hall Current Sensor
Differential Hall architecture with strong common-mode stray-field immunity. Pin-to-pin compatible with ACS724 / MLX91220 for traction inverter and power-supply current sensing.
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.
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.
Programmable TPO Camshaft Position Sensor
Chopper-stabilized Hall with True Power-On (TPO) capability, supporting 5 kHz camshaft magnetic field detection. A single-chip integrated capacitor reduces BOM cost and PCB area.
Crankshaft / Transmission Speed Sensor
For crankshaft and transmission speed measurement, pin-to-pin compatible with TLE4929 / A19520, delivering highly reliable speed signals to the powertrain.
