GENERAL DESCRIPTION
KEY PRODUCT FEATURES
The SX9510 offers proximity sensing. Separate Core and I/O Supplies o 2.7V – 5.5V Core Supply Voltage o 1.65V – 5.5V I/O Supply Voltage 8 - Button Capacitance Controller The SX9510 and SX9511 operate autonomously using a set of programmable button sensitivities & thresholds, plus LED intensities & breathing functions with no external I2C communication required. All devices feature three individual LED driver engines for advanced LED lighting control. On the SX9510, a proximity detection illuminates all LEDs to a pre-programmed intensity. Touching a button will enable the corresponding LED to a preprogrammed mode such as intensity, blinking or breathing. o Capacitance Offset Compensation to 40pF o Adaptive Measurements For Reliable Proximity And Button Detection Proximity Sensing (SX9510) o High Sensitivity o LEDs Activated During Proximity Sense 8-channel LED Controller & Driver o Blink And Breathing Control o High Current, 15 mA LED Outputs 2-C...
