3-axis magnetic sensor which incorporates magneto-impedance (MI) elements to detect magnetic field and a control IC in a small package. The MI sensor features significantly lower current consumption and noise compared with conventional methods, making it suitable for not only for standard ecompass applications but sets requiring even higher accuracy as well.
Ultra-High-Sensitivity contactless current sensor utilizing MI technology. It enables current detection without drawing current into the package. Contactless current sensing minimizes power loss.
For applications requiring open/close or slide detection (i.e. in mobile phones), ROHM offers magnetic switch Hall ICs and Hall ICs for wheel keys and trackballs.
ROHM ambient light sensors feature optical characteristics close to the human eye, enabling automatic backlight adjustment in displays for lower power consumption and optimum visibility.
Rohm's Color Sensor ICs sense Red, Green and Blue light (RGB) and converts them to digital values. The high sensitivity, wide dynamic range and excellent Ircut characteristics makes this IC the most suitable to obtain the illuminance and color temperature of ambient light for adjusting LCD backlight of TV, mobile phone and tablet PC.
ROHM's piezoresistive pressure sensor makes it easy to obtain high accuracy pressure information by performing temperature correction based on proprietary algorithms via an internal IC. Detects differences in height (altitude) through pressure changes in wearable devices, activity monitors, and advanced detection for indoor navigation in smartphones and tablets.
ROHM's Optical Sensor for Heart Rate Monitor incorporates an LED driver and a green light detection photo-diode. It drives LED and provides the intensity of light reflected from body. LED brightness can be adjusted by LED driver current and light emitting period. The photodiode having the high sensitivity for green light, excellent wavelength selectivity and excellent lrcut characteristics achieves accurate pulse wave detection.
ROHM temperature sensor ICs integrate a temperature detection function on a single chip, reducing costs for customers.
The touch screen controller detect the input of the touch sensor arranged on the LCD screen. These touch sensors easily makes a complex input operation intuitive. ROHM's touch screen controller was developed for two kinds of sensors of 4wire resistive touch sensor and capacitive touch sensor. These products can correspond to the demand of various markets.
The ML8540WD is a medium-resolution (approximately 2,000 pixels) infrared image sensor that allows noncontact temperature measurement of an object and easy obtaining of thermal images. The ML8540WD receives infrared rays from an object at 48×47 (2,256) pixels resolution, converts them into voltage through a thermopile, and selects pixels in accordance with external CPU clocks to output signals. The built-in op-amp circuit amplifies the infinitesimal voltage of the thermopile for conventional output signal level. Furthermore, the temperature sensor circuit is used to output a temperature-compensated signal by measuring the chip temperature.
ROHM's optical sensors include high sensitivity, high reliability phototransistors, infrared light emitting diodes, transmission type photointerruptors and reflective type photointerruptors.
