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 8-
channels 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 pre-
programmed 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 correct
touch/no touch information.
The B versions have a different pre-programmed
I2C address.
Low Power
o Sleep, Proximity Sensing: 330uA
o Operating: 600uA
-40°C to +85°C Operation
The SX9512/12B and SX9513/13B are offered in 4.0 mm x 4.0 mm, 20-lead QFN package
20-ld QFN and 24-ld TSSOP packages and operate 4.4 mm x 7.8 mm, 24-lead TSSOP package
over an ambient temperature range of -40°C to Pb & Halogen free, RoHS/WEEE compliant
+85°C.
