    Laser Diode APC Driver ASIC:

    The EDL-1 device is a driver for laser diodes in continuous wave operation which requires only few external components. The broad power supply range of 2.5V to 6V and the integrated protection allow for battery operation with a minimum of two cells. The driver includes integrated circuitry protecting against destruction by ESD, excessive temperature and over current. The driver also filters the laser diode power supply for transients. The power supply is regulated and adapted for the laser diode used by an external resistor at PD. The monitor current acts as a reference and is regulated independent of the influence of temperature and supply voltage (range: 10ľA to 0.5mA). There is only one external capacitor required. In the event of failure, such as over current in the laser path with a lack of feedback, for example, a quick power lockout is activated. The shutdown continues until power is reapplied, permitting a restart. The strain on power packs and batteries is relieved and the laser class is retained even in the event of a disturbance.

    FEATURES
    • CW operation up to 60mA from 2.5..6V supply voltage
    • Simple power adjustment via the external resistor
    • Control loop accuracy better than 5% with changes in temperature, supply voltage and load current
    • Permanent shutdown with excessive temperature and overcurrent (i.e. if the laser diode is damaged or the feedback current path fails)
    • Wide monitor current range from 10µA to 0.5mA
    • One external capacitor is required on output

    MEMS : Laser Scanning Mirror

    E7815 consists of a photodiode and a signal processing circuit for amplifying the photocurrent generated from the photodiode up to 1400 times. Despite a small active area, E7815 provides an output nearly equal to that from photodiodes with a 20 × 20 mm active area. E7815 can be used the same way as a reverse-biased photodiode, and in most cases, it delivers a sufficient output voltage by just connecting a load resistor.

    FEATURES
    • Subminiature, clear plastic package
    • Operation just as easy as using photodiodes
    • Large output current rivaling that of a phototransistor
    • Good linearity
    APPLICATIONS
    • Energy saving sensors for TV brightness controls, etc.
    • Light dimmers for liquid crystal panels
    • Various types of laser power level measurement
