IC-WJSO8 – TBC

The IC-WJSO8, identified as an IC HAUSE 2005 Laser Diode Driver, likely functions as a precision current source designed for driving laser diodes in optical storage or communication applications. Given the “2005” designation, it likely employs a bipolar or BiCMOS process. Key performance characteristics would include a low-noise current output to minimize laser diode RIN (Relative Intensity Noise), an adjustable output current range tailored to common laser diode forward currents (potentially up to several hundred milliamps), integrated soft-start circuitry to prevent current overshoot during power-up, and comprehensive laser diode protection features such as over-current protection (OCP) and reverse voltage protection. Further specifications would include a compliance voltage range, modulation bandwidth (if applicable), and thermal resistance (junction-to-ambient). The package is likely a small outline integrated circuit (SOIC) or similar surface-mount package to minimize board space.
