STEVAL-ILL048V1 Single-channel LED driver for automotive day-time running lights (DTRL) and front lights based on ALED6001 and STM32F103C6T6 Data brief Description The STEVAL-ILL048V1 demonstration board showcases ST s new LED driver chip, the ALED6001. The demonstration also includes an on-board microcontroller that permits full control of the device through a USB connection and dedicated PC GUI. The ALED6001 has been specifically designed to supply a string of medium/high current (50 -1000 mA) LEDs starting from a single low-voltage rail or a car battery. It integrates a boost controller, high-side current sensing feedback circuitry and an external dimming MOSFET controller for superior dimming performance. The boost controller regulates the Features output voltage adaptively, based on the Wide DC input voltage range: from 6 to 24 V requirements of the LEDs, resulting in improved overall efficiency. The maximum output voltage of Integrated boost converter with adaptive output the boost converter is 60 V, allowing the device to voltage for minimum power dissipation drive up to 16 white LEDs in series. Up to 92% boost converter efficiency The brightness of the LEDs is controlled by using Single output LED driver with programmable both PWM modulation and analog current control current capability up to 350 mA (analog dimming). High-side current sensing feedback The device includes dedicated pins to lock External dimming MOSFET driver for superior synchronization with other devices for switching dimming performance noise reduction in multi-device applications. PWM and analog LED brightness control The ALED6001 implements basic protection Up to 60 V output (16 white LEDs) features (OVP, OCP and thermal shutdown) in On-board STM32 microcontroller for simple addition to LED array protection (load device evaluation disconnection, feedback disconnection, and LED overcurrent). USB connection for device control through dedicated PC GUI RoHS compliant January 2015 DocID024269 Rev 2 1/4 For further information contact your local STMicroelectronics sales office. www.st.comSchematic diagram STEVAL-ILL048V1 1 Schematic diagram Figure 1.
