August 22, 2010
The MAX11836 from Maxim Integrated Products, Sunnyvale, CA, is a TacTouch haptic actuator controller for single/multilayer piezo actuators and electroactive polymers in touch-enabled devices. The device adds drive/sense circuitry for connecting up to 4 external force-sense resistors (FSRs) to measure touch pressure. Using FSRs with a capacitive touchscreen controller helps avoid false touches and saves system power. The device simplifies adding haptic feedback to any end application with a touchscreen or touch buttons. Targeted devices include cellphones, portable media players, digital photo frames, multifunction printers, digital cameras, and notebooks.
