IQ Switch® ProxSense® Series
IQS128 / IQS128L Datasheet
IQ Switch® - ProxSense® Series
Single Channel Capacitive Proximity/Touch Controller
The IQS128 / IQS128L ProxSense® IC is a fully integrated capacitive sensor implementing
Dynamic Calibration (DYCAL™) technology: intelligent hysteresis to allow for sensor drift even
during sensor activation.
Features
IQS128 TSOT23-6
DYCAL™ : Intelligent Hysteresis
Internal Capacitor Implementation (ICI) reference
capacitor on-chip
Automatic Tuning Implementation (ATI) -
IQS128L DFN8 (2x3)
Automatic adjustment for optimal sensor performance
Supply voltage: 2.95V to 5.5V
Minimum external components
1-Wire open drain data streaming option
Advanced on-chip digital signal processing
User selectable (OTP):
External synchronisation control or
External control over filter operation
I/O Sink or Source selection
Time-out for stuck key
Proximity and Touch sensitivity selections
IQS128L: Low Power options available
Keys:
Dielectric:
Touch:
Proximity:
Material:
Thickness:
5mm x 5mm or larger (overlay thickness dependent)
Various electrical options (wire / PCB trace / ITO / conductive foil)
Various non-metal materials (i.e. glass, plastic, painted surfaces)
6 mm plastic, 10 mm glass for touch. Very thick overlay possible for proximity
Applications
Occupancy sensors
SAR qualification for Tablet PC’s
On-ear detection for mobile phones
3D glasses
Personal Media Players
White goods and appliances
Advantages
Allows for sensor drift in periods of
activation and non-activation
Improved digital filtering to reduce
external noise
Human Interface Devices
Proximity activated backlighting
Any applications where a touch and
proximity condition can prevail for an
extended period of time with or
without a host controller
Minimal power consumption (<7µA)
when in standby mode (Charge Halt).
Available Options
TA
-40°C to 85°C
