Insights
The AL8891Q represents a significant advancement in LED driver technology with notable technical specifications. The wide input voltage range of 4.5V to 65V coupled with 2A current capability makes it versatile for various automotive lighting applications. The
The comprehensive protection features and CISPR 25 Class 5 EMI compliance make this product particularly attractive for automotive applications. At
While this product launch strengthens Diodes Inc.'s position in the automotive LED driver market, its immediate financial impact is likely to be modest. The automotive lighting market is competitive but growing, driven by increasing LED adoption in vehicles. The product's comprehensive feature set and competitive pricing should help capture market share, but it represents an evolutionary rather than revolutionary advancement.
The automotive-grade qualification and extensive protection features align well with industry trends toward more sophisticated lighting systems in vehicles. However, given DIOD's
Using constant-on-time (COT) control, the AL8891Q achieves simple control-loop compensation and cycle-by-cycle current limiting with a fast transient response without requiring an external compensation capacitor. The device’s switching frequency is adjustable from 200kHz to 2.5MHz, allowing it to optimize efficiency or achieve a smaller inductor size and compact form factor. It incorporates a spread spectrum frequency modulation technique to enhance EMI performance, which eases compliance with the most stringent CISPR 25 Class 5 standard.
The AL8891Q has two independent pins—PWM and analog dimming—for enhanced functionality. PWM dimming, from 0.1kHz to 2kHz, is suitable for high-resolution dimming, and analog dimming is from 0.15V to 2V. It features an internal soft-start function, gradually increasing the inductor and switch current to minimize potential overvoltage and overcurrent at the output.
The device features comprehensive protections with fault reporting, including thermal shutdown with auto-restart, input and constant current undervoltage lockout (UVLO), cycle-by-cycle current limit, and LED-open & short circuit protection to help increase system robustness.
The AL8891Q is available in the thermally enhanced TSSOP-16EP package with an operating temperature range of -40°C to +125°C. It is available at
