Integrated proximity sensor

6 February 2013 Opto-Electronics

Vishay has rolled out a fully integrated proximity sensor that combines an IR emitter, photo-pin-diode, signal processing IC, and 16-bit ADC in one small 4,85 x 2,35 x 0,83 mm surface-mount package.

The VCNL3020 supports an I²C bus communication interface and features an interrupt function and an integrated external emitter driver to extend the sensor’s range.

The device’s 16-bit effective resolution for proximity detection ensures excellent crosstalk immunity, eliminating the need for a mechanical barrier between the emitter and detector.

The sensor’s programmable LED drive current from 10 mA to 200 mA (in 10 mA steps) enables object detection at distances up to 200 mm, and to more than 1 m when the integrated emitter driver is used to drive external emitters.

The VCNL3020 offers excellent ambient light immunity by modulating the emitter signal. Its interrupt function enables the sensor to work independently until a programmable threshold value is reached, and then it wakes up the microcontroller.

Featuring low standby current consumption of 1,5 μA, the device offers a supply voltage range of 2,5 V to 3,6 V and I²C bus voltage range from

1,7 V to 5 V. It operates over a temperature range of -25°C to +85°C and is RoHS compliant.
