LT6101 can operate as a slave of an external controller or as a host. When operating as a host, LT6101 works in synchronization with the clock signal generated by the internal oscillator, cyclically queries the status of each touch button, and activates the external controller in interrupt mode after discovering a specified touch event. The query of the touch button does not require the intervention of the external controller. The identification of specific touch events is automatically completed inside the chip. When there is no touch event, the external controller can enter deep sleep, thereby greatly saving the power consumption of the entire system. Supports host working mode and slave working mode Built-in 11-bit successive approximation capacitor quantizer Support 4-button binary password graphic interrupt trigger Automatic loop query of host touch events Extremely high signal detection accuracy Automatic recognition of various touch events and interrupt triggering Configurable measurement range and measurement accuracy adjustment 251)]Excellent noise suppression and measurement stability Extremely low power consumption, operating voltage 2.8~5.5V
