Smart Home
Motor drive, position sensing and power solutions for smart locks, motorized curtains, robot vacuum actuators and other smart-home mechanisms.
Smart home devices are usually battery powered or run from small adapters, making quiescent current, size and cost critical. RJMICRO Hall switches and latches are small and low power, ideal for limit and wheel-speed detection in locks, curtains and robot vacuum cleaners, while 3D position Hall sensors handle knob and shaft angle feedback.
Systems and scenarios covered
Smart home actuators
- Smart door locks and motorized curtains: motor drive and position sensing
- robot vacuum cleaners: wheel speed and current sensing
- smart appliance knob and shaft angle feedback

For Smart Home, the following RJMICRO devices can be designed in directly — open a device to see full specifications and datasheets.
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.
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 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.
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.
