The CY8CMBR3116-LQXIT is a capacitive touch-sensing controller from Infineon's CapSense® Express™ SmartSense™ series, handling up to 16 button inputs and up to 8 LED driver channels, with built-in proximity detection.
Housed in a 24-UFQFN exposed-pad package (4x4 mm), the CY8CMBR3116-LQXIT is surface-mount and requires a hot-air or reflow station for replacement — not a field-swap part without a rework kit.
