2011671, Драйвер лазерного диода, M типа, 3.6В до 15В, 350мА, мягкий запуск 600мкС, SOIC-8

The 2011671 is a M-type CW Driver for laser diodes in continuous wave operation with laser currents of up to 350mA, which requires only four external components. The wide power supply range up to 15V allows for operation of blue laser diodes. The driver is optimized for M-type laser diodes and allows the operation from a single supply and the connection of the laser diode case with ground. The IC includes integrated circuitry protecting against destruction by ESD, excessive temperature and over-current plus a soft start of the regulator to protect the laser diode when the power supply is switched ON. The IC also filters the laser diode power supply for transients. The regulator is adapted to the laser diode by an external resistor at MDA. The monitor current acts as a reference and is regulated independent of the influence of temperature and supply voltage. The capacitor at CI determines the control time constants and start-up time.

• Rapid soft after power-ON
• Simple power adjustment via an external resistor
• Two feedback inputs permit all current laser diode types to be used
• Modulation via the feedback inputs possible
• Integrated reverse polarity protection
