BS501 -- Touch Integrated Circuit General Description
BS501 is a high-performance capacitive
contactless sensor integrated circuit with strong anti-interference
capability as well as steady and rapid sense capability. It can be
used as touch switches for many materials, such as glass, plastic,
and so on.
Capacitive contactless switches can replace
traditional switches. Traditional switches get wear and become dirty
easily. Contactless keys avoid holing the panel and placing the
buttons. It's easy to maintain and makes your products looks more
beautiful. Many electronic products and appliances have adopted it.
The powerful EasyTouch Tool will generate
touch key's input values automatically in a very convenient way.
Customers could use built-in output options to create the touch
programs easily; this will reduce programmer's loading and shorten
the developing time, as well as speed up the time to market.
