製品概要

概要

The STEVAL-LLL014V1 is a four LEDs strings evaluation kit based on the ALED7709 LED driver configured in boost.

The ALED7709 is an automotive LED driver (AEC-Q100 Grade1 qualified), it includes a DC/DC controller usable as boost or SEPIC, and four low-side constant-current sinks.

The integration of the boost controller with the LED sinks, gives the possibility of adapting the boost voltage for the different LED conditions, minimizing the power dissipation in the ALED7709 and as consequence increasing the overall efficiency.

The evaluation kit houses also the SPC582B60E1, a 32bit automotive grade microcontroller. The MCU controls the ALED7709 via the I2C interface.

The STEVAL-LLL014V1 can be configured and controlled with the STSW-LLL014GUI software, which runs on a PC connected to the board through the USB bus.

The STEVAL-LLL014V1 is designed in the way that ALED7709 can be disconnected from the on board MCU and controlled with an external customer I2C system.

  • 特徴

    • 4.5 to 42V supported input voltage
    • Boost disabled if Vin < 6 V
    • Boost works at 400 kHz with spread spectrum
    • 150mA adjustable current per channel
    • Mixed PWM and analog dimming supported
    • Adaptive boost voltage to comply with different LED conditions
    • NTC to keep under control the LED temperature
    • SPC582B60E1 automotive grade MCU
      • PWM generation for ALED analog dimming
      • PWM generation for ALED FSW synchronization
