IQS572-BL-QNR

Azoteq IQS572-BL-QNR is a Capacitive Touch Buttons integrated circuit (IC) designed for the implementation of touch-sensitive controls. The abbreviation “IC” stands for “Integrated Circuit,” indicating that multiple functions are incorporated into a single chip.

The “Capacitive Touch Buttons” specify the primary function of the IC, which is to detect touch or proximity on capacitive buttons. Capacitive touch technology relies on changes in capacitance to detect the presence or absence of a conductive object, such as a human finger.

The “28-QFN (4×4)” denotes the package type of the IC. QFN stands for “Quad Flat No-Lead,” and 28 indicates the number of pins in the package. This type of package is commonly used for surface-mount ICs, offering a compact and space-efficient design. The “4×4” suggests the physical arrangement of the pins.
