IQS621 combination sensor
IQS621 combination sensor

AUSTIN, Texas (PRWEB) March 01, 2018 -- Azoteq, a pioneer in sensor fusion, today announced the release to market of the IQS621. The IQS621 ProxFusion® IC is a multi-functional, ambient light sensing (ALS), capacitive, Hall-effect and inductive sensor designed for applications for which any or all of the technologies may be required. The IQS621 is an ultra-low-power solution designed for short- or long-term activations through any of the sensing channels.

For the first time, a designer is now able to employ four sensing technologies by using just a single component.

The IQS621 complements the existing part numbers in Azoteq’s ProxFusion® combination sensor family and adds ambient light sensing to the portfolio. The device is available in a low-profile UOLG (2.8 x 2.5 x 0.6 mm) 9-pin package, with minimal external components required.

The ProxFusion® family builds on Azoteq’s decade of capacitive-sensing experience and adds unique sensing capabilities in single-chip solutions.

“The IQS621 once again pushes the boundary in terms of sensor integration into a single IC,” said Jean Viljoen, Azoteq’s VP of Marketing. “For the first time, a designer is now able to employ four sensing technologies by using just a single component.”

Samples, production quantities and evaluation kits are available through Azoteq’s distribution channels and popular online distributors.

Features:

Unique combination of sensing technologies

  • Capacitive sensing
  • Ambient light sensing (ALS)
  • Hall-effect sensing
  • Inductive sensing

Capacitive sensing

  • Full auto-tuning with adjustable sensitivity
  • 2 pF to 200 pF external capacitive load capability
  • Down to 10 aF resolution
  • Enhanced temperature stability

Ambient light sensing (ALS)

  • Absolute lux output
  • Human eye response compensated
  • ALS range output (0 – 10)
  • Dual threshold detection for day/night indication with hysteresis

Hall-effect sensing

  • On-chip Hall-effect measurement plates
  • Dual direction Hall switch sensor UI
  • Two-level detection (widely variable)
  • Detection range 10 mT – 200 mT

Inductive sensing

  • Two-level detection and hysteresis for inductive sensing
  • Only external sense coil required (PCB trace)

Automatic Tuning Implementation (ATI) – performance enhancement (10 bit)

  • Minimal external components
  • Standard I2C interface
  • Optional RDY indication for event mode operation

Low power consumption:

  • 75 uA (100 Hz response, 1 ch inductive)
  • 95 uA (100 Hz response, 2 ch Hall)
  • 75 uA (100 Hz response, 3 ch capacitive)
  • 60 uA (100 Hz response, ALS)
  • 25 uA (20 Hz response, 1 ch inductive)
  • 25 uA (20 Hz response, 2 ch Hall)
  • 20 uA (20 Hz response, 3 ch capacitive)
  • 18 uA (20 Hz response, ALS)
  • 2.5 uA (4 Hz response, 1 ch cap. wake-up)

Supply voltage: 1.8 V to 3.3 V

Low profile UOLG - 2.8 x 2.5 x 0.6 - 9-pin package

Applications:

  • Mobile electronics (phones/tablets)
  • IoT, security, home automation and lighting control
  • White goods and appliances
  • Wearable devices
  • Human interface devices
