Diodes Incorporated has expanded its portfolio of devices supporting automotive exterior illumination with the introduction of the AL5873Q three-channel linear LED driver targeted at simplifying rear lamp cluster designs.

Rated for 125°C ambient temperature operation, this automotive-compliant, AEC-Q100 Grade 1 qualified device meets the demands of next generation vehicle design. Each of the AL5873Q’s channels can drive up to 250mA, and is set via two reference resistors, which are connected to the driver IC’s REF1 and REF2 pins. Support for two different LED current levels enables more streamlined lighting systems - as the same LEDs can be used in rear lamp clusters for tail and brake lamps.

The AL5873Q has analog and master PWM dimming control functionality, supporting a maximum PWM frequency of 1kHz (more info).
