The IS31CS8979-QFLS2-TR from Lumissil Microsystems 18-Channel Intelligent LED driver that is designed for automotive and industrial lighting applications. It requires an input voltage of 3-5.5 V. It supports up to 18 high-voltage PWM-modulated constant current sources with a maximum output of 60 mA per channel, ensuring accurate and vibrant LED lighting. This LED driver consists of 8-bit PWM resolution, 8-bit dot correction, and global current control, providing precise RGB color mixing and EMI reduction through selectable phase delays and spread spectrum. It has a built-in MCU that consists of 32 MHz CPU core, 64 KB e-Flash with ECC, three watchdog timers, and versatile interfaces such as I2C, SPI, UART/LIN, and PWM duty.

This LED driver supports advanced functions like pattern animation, in-system programming, and fault detection for open circuits, short circuits and thermal conditions. Additionally, it can cascade to synchronize multiple devices, making it a scalable solution for diverse lighting needs. This RoHS/ TSCA-compliant LED driver is available in a surface-mount package that measures 6 x 6 mm and is ideal for industrial and appliance LED lighting, ambient lighting, indication light animations and welcome lighting applications.
