The SSP8011AM is a low-cost and low-power single-key capacitive touch sensor IC, which provides single-channel touch sensing channels. Built-in voltage regulator circuit, few peripheral components, simple design, only a few components can complete the hardware design. Provides 2 output modes, high/low level output optional. It also provides a Reset function after a maximum button press time of 9 second. The sensitivity of the touch-sensitive keys can be adjusted as needed by adjusting the capacity of the external capacitance (CS), which increases the operability of the product and makes the design more flexible and versatile.
