The IS31CS9310 from Lumissil Microsystems is an Automotive-Qualified LED Driver and Controller that is ideal for LED control, LED lighting control, and industrial HMI control (white goods and appliances) applications. It requires an input voltage of 3-5.5 V (LED). This AEC-Q100 Grade 1-qualified driver/controller consists of a RISC-V EMC core, memory units, clock sources, timers, host interfaces, analog/digital peripherals, a touch-key controller, a melody controller, and an LED control/driver. It uses the built-in microcontroller for processing touch keys, active proximity sensing signals, and LED controls. This IC’s touch-key controller supports self-capacitance mode, mutual-capacitance mode (optional), and proximity sensing. It enables up to 16 keys with the self-capacitance mode, while the mutual sensing allows for 8 x 8 key matrix scanning. 

This TSCA-compliant LED driver/controller supports up to 8 x 12 matrix LEDs consisting of 8 PMOS switches with scanning logic and 12 pulse width modulation (PWM)-controlled current sources. It uses 14-bit precision tone generation, wide octave, and pulse/amplifier output for melody control. This driver IC has built-in 16/32 MHz clock reference (with spread spectrum) and watchdog timers for efficient timing synchronization during control. It can be controlled using I2C, EUART, and SPI interfaces and uses analog/digital peripherals for accurate data readout. This RoHS-compliant LED driver is available in a surface-mount package that measures 9 x 9 mm.
