VCNL4035X01

Introducing the infrared PHOTOSENSORS IC (VCNL4035X01) that can also be used in automobiles.
Gesture sensing is also supported.

This IC contributes to the realization of a variety of proximity and illuminance sensing applications.
Recently, due to the impact of COVID-19, touchless operation is required in various situations, and this IC makes this possible.In addition, when used in combination with an external IR emitter, this IC can also be used for gesture applications, making some operations possible without touching.
Potential applications include kitchen appliances, medical equipment, construction machinery, in-vehicle infotainment, laptops, and smartphones.

Features

Can be used in environments up to 110°C

Due to their characteristics, optical products tend to have an operating temperature range of less than 100°C, but this product can be used in an environment of 110°C (Tj = 125°C).

External infrared LED detects surface and distance

By increasing the drive voltage, it can drive six external infrared LEDs, enabling gesture sensing on surfaces (such as DISPLAY) and extending the proximity sensing distance to up to two feet.

Distance measurement accuracy of less than 1mm

The built-in PHOTO DETECTORS of this device has a high resolution of 16 bits, and can measure the distance to an object close to the device with an error of less than 1 mm. This allows it to detect things like surface deflection (force sensing).

Can be used outdoors

Outdoors, this IC is particularly exposed to various types of noise light, including sunlight.The built-in optical FILTERS and DCkill function can remove infrared wavelengths contained in noise light, making it possible to use it outdoors.

Use Cases

Kitchen appliances, medical equipment, construction machinery

Outdoors, this IC is particularly exposed to various types of noise light, including sunlight.The built-in optical FILTERS and DCkill function can remove infrared wavelengths contained in noise light, making it possible to use it outdoors.

Laptops, smartphones

This IC has an extremely low profile of just 0.75mm, so even if a gesture sensor function using this IC is installed, the impact on the thickness of the device is minimal.In addition, since it can detect weak infrared light, it can sense correctly even when using DISPLAY with poor transmittance.

In-vehicle center cluster

This device can FILTERS noise light from the sun, headlights, etc., enabling accurate light sensing in any location.
Gesture sensing also enables the driver to operate various equipment without shifting their gaze.
