RM1281AST6x Overview:
The RM1281AST6x series chips adopt CDC technology, which can achieve capacitance change detection with fewer external components.
The chip has a high power voltage suppression ratio, which can suppress the occurrence of accidental contact, ensuring that the chip still has high reliability under harsh environmental conditions.
The RM1281AST6x series chips have a wide voltage operating range, low power consumption operating mode, and have industrial grade operating temperature range, automatic calibration function that adapts to the environment, and resistance to voltage fluctuations. They can provide a wide range of products such as intelligent switches, wear detection, and watches.
