The AT42QT1010 and AT42QT1011 have three speed settings:
n
For devices where a quick response is required, a fast response setting is available with a 12.2 ms maximum response time.
n
It is also possible to set up the device for low power consumption, at the expense of a slower response time of up to 88.6 ms.
n
A third option is to synchronize the device to an external clock which makes it possible to synchronize several ICs in the same
device. This technique can be used to enhance noise immunity by syncing to a noise source such as mains. The response time
is then dependent on the external clock.
When the device is in low power mode or when the synchronisation mode is selected, a HeartBeat output
is available. This provides a pulse whilst the device isn’t in detect which can be used to verify the device is
working correctly.

The AT42QT1010 and AT42QT1011 are identical apart from their behavior
when the sensor is “in detect” for an extended period.
The AT42QT1010 has a “maximum on” duration of ~ 60s. If there is an ob-
struction on the sensor, the device output will go low after the “maximum
on” detection period, so that subsequent touches can be detected.
The AT42QT1011 has no timer and the device will remain on whilst the
sensor is activate.
Speed Settings
AT42QT1012
The device is similar to the AT42QT1010 and AT42QT1011 but it has touch-on/touch-off (toggle) functionality and a power down
timer.
Auto Off Timers
The QT1012 has a number of options for automatic power down which can be used to conserve power in situations where the
device could be left on inadvertently. There are predefined power down settings which can be used to power the device down after
15 minutes or 60 minutes. There is also the option for no power down timer so the device remains on until touched again.
