Laser Diode Driver ELM185 Series

ELM185 is a laser diode driver (LD driver IC) with an integrated APC (Automatic Power Control) circuit.

**Overview** The ELM185xB is a bipolar structure laser diode driver IC that incorporates an APC circuit consisting of a reference voltage source and an error amplifier. It stabilizes the laser output against changes in supply voltage and temperature using the reference voltage source within the IC. The driver output can drive laser currents of up to 400mA. Due to its compact package, it allows for implementation in a minimal area. As a protective feature, it includes a cutoff circuit for abnormal high temperatures and has the capability to limit the laser drive current in case of control loop failure. The current limit value can be set using an external resistor. It also has a built-in surge-absorbing Zener diode (Vz≈7V) between the power supply (VCC-GND) to prevent laser diode damage. It can drive multiple types of laser diode modules (LDM). Furthermore, it is possible to use the built-in constant current setting function for open-loop constant current driving, rather than driving through APC control, allowing it to be used as an open-loop constant current driver for laser diodes, high-brightness LEDs, and more. *For more details, please refer to the catalog or feel free to contact us.*
