IQS621 combination sensor
For the first time, a designer is now able to employ four sensing technologies by using just a single component.
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.
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.
