ProxSense® Series
IQS229 Datasheet
Single Channel Capacitive Proximity/Touch Controller for SAR Applications
The IQS229 ProxSense® IC is a self-capacitance controller designed for devices that are
required to meet SAR regulations. The IQS229 can detect a long term presence through
movement detection algorithms when the device (e.g. tablet or cell phone) is handled.
The IQS229 can be used in any application requiring long-term activation by animated objects.
A movement detection algorithm will indicate the presence of a user and aid in the long-term
stability of the solution. The device operates standalone and can be configured via digital
inputs.
Features
• SAR compliance in mobile devices
according to the IEC 62209-2 ed1.0
standard and the FCC standard (KDB
616217 - D04 SAR for laptop and tablets
v01)
• Failsafe firmware/hardware design
• Automatic Tuning Implementation (ATI) -
Automatic adjustment for optimal sensor
performance
• Minimal external components
• Standalone operation
• 25mm detection distance
• Up to 60pF sensor load
• On-chip movement detection algorithm
• Internal Capacitor Implementation (ICI) –
reference capacitor on-chip
• Configuration settings via external pins
• Activation threshold
• Movement filter threshold
• Activation time-out
• Supply voltage: 1.8V to 3.6V
• Low power consumption: 30uA (sub 10uA
in sleep mode)
• Low profile DFN10 package (3x3)
Applications
• SAR detection for tablets and mobile
phones
• SAR detection for wireless charging
stations (operating frequency > 100 MHz)
• SAR detection for USB dongle-type
devices
• Movement detection devices (anti-theft)
• Reed relay replacement
• White goods and appliances
• Human Interface Devices
• Proximity activated backlighting
• Applications with long-term activation

run which can be run periodically in order to
run with optimal sensitivity.
1.2.3 Movement filters
The movement filter runs continually and
the dedicated digital output will activate for
a time depending on the intensity of the
movement.
1.2.4 External control
The movement output (optional line to
connect to master device) can be used to
signal a “reseed” or “sleep mode”. A short
pulse will force the reference counts (long-
term average) to match the actual counts
(capacitance of sensor). By writing the pin
low for a longer time, will force the IC into
sleep mode for low current consumption
(2uA + required pull-up on movement pin).
In sleep mode the output pin is written low
in order to minimise current consumption.
1.2.5 Low power options
As mentioned in the section above, a
charge halt will initiate the sleep mode. The
device will reset and return to normal power
as soon as the line is released.
1.3 Applicability
All specifications, except where specifically
mentioned otherwise, provided by this
datasheet are applicable to the following
ranges:
Temperature:-40C to +85C
Supply voltage (VDDHI): 1.8V to 3.6V
