Operating from a single 1.75V to 5.5V supply, it draws just 4 mA typical, making it suitable for both battery-powered handhelds and 5V logic systems. ## Supply flexibility and LED drive The wide 1.75V to 5.5V supply range means the part runs from a single lithium coin cell (down to 1.8V) up to a standard 5V USB rail without a regulator. The 4 mA supply current at full operation keeps the battery budget low for always-on touch interfaces. Each of the up to 4 LED driver channels can sink current for status or backlight LEDs, reducing external component count. The part does not support proximity detection — it registers touch only on contact, which is the expected behavior for button-replacement applications. ## Package and board integration Housed in a 16-UFQFN (3x3 mm) package, the CY8CMBR2044-24LKXIT requires a surface-mount assembly process. The 16-QFN footprint with 0.5 mm pitch demands careful PCB layout for the exposed pad thermal and ground connection. ROHS3 compliance is confirmed, and the active lifecycle status means no end-of-life planning is needed for new designs.","metaTitle":"CY8CMBR2044-24LKXIT CapSense Express 4-Button Touch","metaDescription":"CY8CMBR2044-24LKXIT CapSense Express capacitive touch controller, 4 inputs, 4 LED drivers, 1.75-5.5V, -40 to 85°C, 16-QFN.
