IQS213/A Datasheet

IQSwitch^®- ProxSense^®Series

3-Channel Capacitive Touch/Swipe Function Controller

Overview

Unparalleled Features



Sub 5µA* current consumption (“Zero-Power” electronic switch).

Internal Capacitor Implementation (ICI) – Reference capacitor on-chip

Automatic Tuning Implementation (ATI) - Automatic tuning for optimal operation in various

environments & compensation against sensitivity reducing objects



IQS213A advised for applications with high load-capacitances and high sensitivity

requirements.

The IQS213(A) ProxSense^®IC is a fully integrated two or three channel capacitive swipe function

sensor with market leading sensitivity and automatic tuning of the sense electrodes. The

IQS213(A) provides a minimalist implementation requiring few external components, with OTP-

option settings and an I²C-compatible interface that allow configuration for numerous applications.
