Product overview

Description

The EV-L99LDLH32GEN board provides an easy way to connect L99LDLH32 into the existing system.

To connect a lighting load, it is necessary to design a specific adapter board according to the chosen OLED panel.

  • All features

    • General
      • Application board with two L99LDLH32
      • Designated to drive generic OLED panel
      • CAN FD light compatible serial interface, protocol handler, draft specification proposal (DSP) available from CAN in automation (CiA)
      • High precision oscillator integrated, no external quartz required
      • QFN48L 7x7 with exposed pad
      • Time out watchdog with limp-home
      • Low standby current
      • Stand-alone/fail-safe and bus mode operation
      • Direct drive (one direct input), for one function group supporting ASIL requirements
      • Widest configurability by embedded non-volatile and volatile memories
      • Operating supply voltage range from 5.5 V to 40 V
      • Operating temperature range from -40 °C to 150 °C
    • Linear regulators section
      • 32 constant current output channels, high-side configuration
      • Output current from 1 mA to 15 mA, parallelizable outputs
      • Output voltage up to 35 V
      • Feedback voltage to external pre-regulator, to optimize the regulation voltage minimizing overall power dissipation
      • Current setting per channel by 8-bit DAC
      • Analog dimming, 8-bit PWM channel individual exponential brightness control and 8-bit global PWM dimming
      • Programmable PWM frequency
      • Slow turn on/off time, gradual outputs delay and dithered clock, for better EMC performances
    • Protection and diagnostic
      • Integrated 8-bit ADC, for full and flexible diagnostic
      • One dedicated line for fault bus
      • Temperature warning (one threshold)
      • Overtemperature shutdown
      • Short circuit and open load detection and protection
      • Automatic LED current derating, through external NTC measurement and device junction temperature (TJ)
