Diodes Incorporated AL58818Q 18-Channel Linear LED Driver comprises 18 programmable LED current channels, each with internal 12-bit Pulse Width Modulation (PWM) and 6-bit global current dimming for color and brightness control through an I2C or SPI digital interface. AL58818Q is ideal for up to six RGB LED lighting modules with three programmable banks (A, B, C) for software control of each color or 18 single-color LEDs with independent dimming for each channel. An external resistor can set up the global output current of all 18 channels. Each channel current can be digitally configured up to the thermal limitation of the package. The AEC-Q100 (Grade 1) qualified device operates over a -40°C to +125°C ambient temperature range and is available in a W-QFN5050-40/SWP (Type A1) MSL level 1 package.
