2. Overview
The BS81x series chips have 2 to 16 touch buttons, which can be used to detect the touch action of a human hand on an external touch button. The chips of this series have a high degree of integration, and only a few external components are needed to realize the detection of touch buttons.
The BS81x series provides serial and parallel output functions, which facilitate communication with external MCUs, and realize the purpose of device installation and touch pin monitoring. A special integrated circuit is used inside the chip, which has a high power supply voltage rejection ratio, which can reduce the occurrence of key detection errors. This feature ensures that the chip still has high reliability in applications with unfavorable environmental conditions.
This series of touch chips have automatic calibration function, low standby current, resistance to voltage fluctuations and other characteristics, providing a simple and effective implementation method for various touch button applications
