ROHM Sensors

Interface

Interfaces are devices used to control sensor operation (not the sensor element itself) and for amplifying, analyzing, and processing output signals from the sensor. They help maximize sensor performance and make it easy to achieve new functions and uses.

Capacitive Switch Sensor ICs

VQFN024V4040

VQFN024V4040

ROHM capacitive switch ICs utilize a original capacitance detection circuit to achieve both high noise tolerance and high sensitivity.
Stable detection of minimal changes in capacitance allows for reliable sensing of finger contact, even when using thicker cover and protective films.

Features

  • High sensitivity with high noise immunity
  • Integrated LED dimming, press and hold, and auto calibration functions
  • Built-in noise/offset/temperature drift cancellation control functions
  • Supports matrix configuration

Applications

  • Printers, TVs, Audio Players,and Other Consumer Devices
  • Home Appliances/Equipment (i.e. Refrigerators, AC, Air Purifiers)

Human Presence Sensor IC

Human Presence Sensor IC

SSOP-B14

ROHM's human presence sensor IC is a pyroelectric infrared sensor amplifier equipped with a detection function, high-sensitivity amp for amplifying small input signals, and constant voltage source that supplies stable voltage to the sensor. Integrating multiple optimized functions into a single chip saves space along with standby power. In addition, the sensitivity can be customized by simply changing the circuit constants to meet application requirements.

Features

  • Built-in small-signal amp
  • Integrated sensor signal output comparator
  • Internal voltage regulator

Applications

  • Lighting Switches
  • Security Systems
  • TVs, PC Displays
