OVERVIEW
The QT118H is a digital burst mode charge-transfer (QT) sensor designed specifically for touch controls; it includes all hardware and signal processing functions necessary to provide stable sensing under a wide variety of changing conditions. Only a few low cost, non-critical discrete external parts are required for operation.Figure 1-1 shows the basic QT118H circuit using the device, with a conventional output drive and power supply connections. Figure 1-2 shows a second configuration using a common power/signal rail which can be a long twisted pair from a controller; this configuration uses the built-in pulse mode to transmit the output state to the host controller.
â— Less expensive than many mechanical switches
◠Projects a ‘touch button’ through any dielectric◠100% autocal for life - no adjustments required
â— No active external components
◠Piezo sounder direct drive for ‘tactile’ click feedback
â— LED drive for visual feedback
â— 2.5 ~ 5V single supply operation
◠10µA at 2.5V - very low power drain
â— Toggle mode for on/off control (via option pins)
â— 10s or 60s auto-recalibration timeout (via option pins)
â— Pulse output mode (via option pins)
â— Gain settings in 3 discrete levels
â— Simple 2-wire operation possible
â— HeartBeatâ„¢ health indicator on output
â— Pb-Free package
APPLICATIONS -
â— Elevator buttonsâ— Toys & games
