Powertrain
Covering transmission, fuel tank, engine peripherals and traction systems — chip solutions for electronic shifters, urea pumps, electronic oil pumps, electronic throttle, EGR valves, turbo actuators, fuel level and crank/cam position sensing.
Powertrain
Chip technology underpins innovation, electrification and intelligence across the automotive industry, and powertrain is one of RJMICRO core application areas, spanning both internal-combustion and electric drive systems.
On the electric drive side, linear and integrated current sensors handle three-phase traction inverter current sensing. On the combustion side, Hall switches and latches, 3D position Hall sensors, linear Hall sensors and camshaft / crankshaft position sensors form a complete position and speed sensing solution.

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.
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.
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.
