ATMXT144UD-AMBI2CVAO maXTouch Touchscreen Controller
The ATMXT144UD-A is the smallest Automotive qualified touchscreen controller in a VQFN-56 package with wettable flanks, aimed at smart surfaces and multi-function displays up to 4.3”.
Excellent intrinsic SNR of this latest maXTouch family enables detection and tracking of multi-finger thick gloves through a wide variety of overlay materials and thicknesses, even in the presence of moisture. This SNR combined with a high acquisition speed provides a fast, accurate and reliable a touch position.
The ATMXT144UD-A incorporates a new low power mode for wake-up on touch, this enable the system to go into a wait-for-touch mode while consuming less than 50uA and to wake-up by a touch event anywhere on the touch surface.
This technology also enables adaptive touch utilizing self-capacitance and mutual-capacitance measurements so all touches are recognized and false touch detections are avoided.
The controllers also incorporate a new self and sensor diagnostic function, which constantly monitors the integrity of the touch system. The new ATMXT144UD-A device brings these smart diagnostic features in support of the Automotive Safety Integrity Level as specified in ISO26262.
Please contact your Baoxingwei sales office for pricing information and to place an order.
