STEVAL-ILL048V1:Single-channel LED driver for automotive day-time running lights (DTRL) and front lights based on ALED6001 and STM32F103C6T6

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 output voltage adaptively, based on the requirements of the LEDs, resulting in improved overall efficiency. The maximum output voltage of the boost converter is 60 V, allowing the device to drive up to 16 white LEDs in series.

The brightness of the LEDs is controlled by using both PWM modulation and analog current control (analog dimming).

The device includes dedicated pins to lock synchronization with other devices for switching noise reduction in multi-device applications.

The ALED6001 implements basic protection features (OVP, OCP and thermal shutdown) in addition to LED array protection (load disconnection, feedback disconnection, and LED overcurrent).
