IQS550/572/525-B000 – Capacitive Trackpad/Touchscreen Controller

Projected capacitive controller with proximity, touch, snap, trackpad outputs and gestures

The IQS5xx-B000 is a projected capacitive touch and proximity trackpad/touchscreen

controller implementation on the IQS550, IQS572 and IQS525 platforms. The IQS5xx-

B000 features best in class sensitivity, signal-to-noise ratio and automatic tuning of

electrodes. Low power proximity detection allows extreme low power operation.

Main Features

 Proximity, touch and snap* on each channel

 Multi-touch support up to 5 fingers

 Single and multi-finger gestures

 3584 x 2304 max resolution (IQS550)

 Scale, orientation and electrode layout selection

 I²C communication interface

 ATI: automatic tuning for optimum sensitivity

 Supply Voltage 1.65V to 3.6V

 Proximity low power operation (<10uA)

 3 Active and 2 low power modes

 Event and streaming modes

 Internal voltage regulator and reference capacitor

 On-chip noise detection and suppression
