TTP226 8-Way Capacitive Touch Sensor Module

Description

TTP226 8-Way Capacitive Touch Sensor Module is a capacitive sensing design for touch pad detection and can sense up to 8 touch keys. Replacing manual switches and buttons with capacitive touch pads is the main purpose of this IC.

It senses touch based on change in capacitance. TTP226 can handle 8 touch pads and has 8 direct output pins. It also has an option of using a serial interface mode.

TTP226 has low power consumption and can operate on supply voltage ranging from 2 to 5.5V.

Features:

• On-board TTP226 capacitive touch induction IC
• Operating voltage 2.0V~5.5V
• Operating current typical 100uA, max 160uA at VDD=3V
• The output refresh rate about 55Hz at VDD=3V
