1. Overview
1.1 Introduction
SC02B is a self-correcting capacitive touch sensor, which can detect whether 2 induction plates
are touched. It can induce the changes in capacitance through any nonconductive medium (such as
glass and plastics). Such capacitive sensing switches can be applied to many electronic products,
increasing the added value of products.
1.2 Characteristics
◇ 2 completely-independent touch-sensitive buttons
◇ Maintain automatic correction without external intervention
◇ Complete joggling removal treatment of button output
◇ Parallel one-to-one output
◇ All buttons share a sensitivity capacitor
◇ Different length of induction line will not result in different sensitivities
◇ Operating voltage of 2.5V - 6.0V
◇ Environmental-friendly SOP8 encapsulation meeting the RoHS instructions
1.3 Application
◇ Replace mechanical switches
◇ Home applications (TV, display, keyboard)
◇ The human-machine interface for tools and interactive games
◇ Access control keys
◇ Lamp control switch
◇ The panel of sealed keyboards
1.4 Encapsulation
SOP8 encapsulation is
adopted for SC02B
