Consumer Electronics & Wearables
Position sensing, motor drive and power management for wearables, personal-care appliances and portable consumer electronics.
Wearable and personal-care consumer electronics impose extreme demands on size, quiescent current and tactile feel: lid and cover detection, knob and hinge angle feedback and vibration-motor drive all rely on small, low-power position and magnetic sensing devices. RJMICRO Hall switches and latches plus 3D position Hall sensors cover these compact mechanisms, while wide-input LDOs provide stable always-on, low-quiescent-current power for portable devices.
Systems and scenarios covered
Wearables and portable devices
- TWS earbuds and charging cases: lid open/close and in-place detection
- smart watches and bands: crown / knob angle feedback
- portable power banks: power management
Personal care and small appliances
- Electric toothbrushes, shavers and massagers: vibration / rotary motor drive and speed detection
- multi-position knob sensing

For Consumer Electronics & Wearables, 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.
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.
