Microchip Technology Inc., announced a new family of projected-capacitive touch controllers—the MTCH6102 with industry-leading low-power performance.
These turnkey projected-capacitive controllers make it easy for designers to add contemporary touch and gesture interface designs to cost-sensitive applications.
This MTCH6102 facilitates design integration of capacitive scanning for touchscreens and touchpads including 11 single-finger gestures to swipe, scroll or double tap.
The MTCH6102 enables flexible, scalable solutions to support PCB, ITO or FPC sensors up to 15 channels. It supports cover lenses up to 3 mm plastic and 5 mm glass and configurable sleep/idle frame rates to optimize for most power budgets with active mode as low as 12 μA. Microchip offers its free Configuration Utility to allow designers to make fast customizations.
Microchip also provides designers with the firmware library for further optimization and control if needed.
The MTCH6102 family serves a wide range of applications in the consumer-electronic (e.g., remote controls, gaming devices, wearable devices such as headphones, watches, fitness wristbands, and track pads), and automotive markets (e.g., automotive interior controls and control panels), among others.
“Microchip’s turnkey, low-cost controller offers the lowest power projected-capacitive touch solution in the industry to maximize battery life in cost-sensitive applications,” said Fanie Duvenhage, director of Microchip’s Human-Machine Interface Division.
“The MTCH6102 provides developers with a flexible touch-sensing solution for smaller touch areas to optimize common constraints of size, power and cost that are critical to applications such as wearable devices, remote controls, gaming devices and track pads.”
