Overview
WIRELESS & SENSING PRODUCTS SX9512/12B/13/13B 8 Capacitive Buttons, LEDs and Proximity Controller with Analog Outputs DATASHEET GENERAL DESCRIPTION KEY PRODUCT FEATURES The SX9512/12B and SX9513/13B are 8–button capacitive touch sensor controllers that include 8channels of LED drivers, a buzzer and analog outputs designed ideally for TV applications.
The SX9512/12B 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 Support Metal Overlay UI Design (SX9512/12B) The SX9512/12B and SX9513/13B 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 SX9512/12B, 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.
8 - Button Capacitance Controller o Capacitance Offset Compensation to 40pF o Adaptive Measurements For Reliable Proximity And Button Detection Proximity Sensing (SX9512/12B) 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 Whenever the capacitive value changes from 2-Channel Analog Output, 6-bit DAC Programmable either a proximity detection or finger touch/release, the controller informs the host processor through the analog output(s) or an open drain interrupt and an I2C register read.
Control Programmable Buzzer Simple (400kHz) I2C Serial Interface The SX9512/12B and SX9513/13B do not require o Interrupt Driven Communication via NIRQ Output additional external dynamic programming support Power-On Reset, NRST Pin and Soft Reset or setting of parameters and will adapt to humidity and temperature changes to guarantee correc...
