Insights
The AL5887Q LED driver represents a significant technical advancement for automotive lighting applications. The 36-channel capability with RGB support and 70mA per channel output positions this product well in the growing automotive ambient lighting market. Key differentiators include the
This product launch aligns with the growing trend of vehicle premiumization and increasing demand for sophisticated lighting solutions in the automotive sector. The automotive LED lighting market is experiencing robust growth, driven by both aesthetic and functional requirements in modern vehicles. The AL5887Q's competitive pricing at
The AL5887Q supports up to 12 RGB LED modules with three programmable banks (A, B, C) for software control of each color. An external resistor sets the output current of all 36 channels. Using the hardware-selectable digital interface (INT_SEL pin), lighting designers have the option to select either I²C or SPI for full system programming flexibility. Each channel current is configurable up to 70mA, enabling full optimization of the visual clarity of the LEDs, which avoids the need for paralleling. Designers also benefit from the device’s automatic power-saving mode of 15µA and ultra-low quiescent shutdown of 1µA when all LEDs are off for more than 30ms, helping minimize unnecessary energy draw from the car’s battery.
The device has multiple protection features, including an open drain FAULT pin for fault reporting and overtemperature protection (OTP) with pre-OTP warning. The individually addressable fault mask registers and open/short registers allow designers to enable and disable fault reporting for each of the 36 channels within the lighting system. Any unused RGB channels can be disabled by the LED configurable registers.
The AL5887Q features a built-in 16MHz oscillator for PWM dimming, eliminating the need for an external clock, which reduces the PCB footprint of the lighting modules, eases design and layout, and lowers bill-of-material (BOM) costs. To optimize color mixing and minimize audible noise, it uses a 12-bit PWM addressable register along with a 30kHz internal PWM generator. The device supports deep PWM dimming by modulating the duty cycle of the constant current from
The AL5887Q is specified for an operating temperature range of -40°C to +125°C and is available in the small-footprint wettable W-QFN6060-52/SWP (Type A1) package, occupying only 6mm x 6mm.
