Silicon Labs CPT212B and CPT213B TouchXpress capacitive touch controllers

Friday, 15 September, 2017 | Supplied by: Mouser Electronics (Hong Kong) Ltd

Silicon Labs’ CPT212B and CPT213B TouchXpress capacitive touch controllers eliminate time-consuming firmware development, providing a simple turnkey solution for adding touch-based designs to a wide range of products, including home appliances, medical equipment, consumer electronics, instrument and control panels, and lighting control.

The controllers provide a fast and easy way for design engineers to add low-power capacitive touch interfaces to embedded designs. The I²C interface provides an easy way to track the status of touch sensors, and an interrupt pin can wake the host processor from sleep after touch detection.

The CPT212B device features up to 12 sensor inputs and features ultralow-power operation, rated at 200 µA in optimised active mode and 1 µA in sleep mode. The CPT213B device offers up to 13 sensor inputs and adds IEC 60730 Class B safety library support, designed for preventing unsafe operation of household appliances.
