Temperature Sensor ICs
ROHM's temperature sensor ICs feature a high accuracy reference voltage supply, comparator, constant current circuit, and a temperature detection element into a single chip, eliminating troublesome circuit design. Temperature detection capability is enabled by simply connecting the IC to the set substrate, saving space.
- Analog Output Type with ±2.0°C accuracy
- Standard Thermostat Type [BDExxx ] covers range from -20°C to 120°C
- Low Power Thermostat Type [BDJxxx] covers range from 55°C to 90°C

Touch Sensors
ROHM touch screen controller detect the input of the touch sensor arranged on the LCD screen or dedicated butttons. These touch sensors allow the easy implementation of intuitive input operation. ROHM's touch screen controllers are available for 4wire resistive touch sensor and capacitive touch sensor.
- Enabling 2 point detection on 4 wire resistive touch screens
- Implement gesture recognition on 4 wire resistive touch screens
- Capacitive touch solutions for up-to 36 switches [BU21078]

IR and Optical Sensor ICs
ROHM offers a wide selection of optical components including discrete components like photo transistors and IR-LEDs as well as integrated modules such as IrDA, remote control modules, tilt sensors and photo-interrupters. Compared to RF solutions IR based communication offeres avantages like high level of sequrity,more design freedom ( compatibility for future redesigning of set ) which makes them interesting for a wide range of applications.
- Ultra-low power consumption
- Broad line-up
- Small package options
