Touchscreen controller offers HA1 variants for safety

This touchscreen controller is optimised for display panels up to 9.7-in with up to 32 transmit lines and 20 receive lines and a maximum of 640 nodes.

HA1 variants of the ATMXT640UD are specifically designed for applications where functional safety is required.

These devices are IEC/UL 60730 Class B certified and offer unique safety-related features that enable system shut off through an intuitive soft button on a touchscreen, removing the requirement for an external safety certified stop or cancel button and associated microcontroller.

The ATMXT640UD allows an appliance to detect touchscreen-related failures and shut down the appliance automatically through various self-test functions.

Applications include human-machine interfaces (HMIs) for industrial, appliance, or medical designs.
