Concentrated into a super compact size, the IC that plays a key role in the next-generation laser driver.
Laser Diode Driver IC "ELM185BB"
The ELM185BB is a bipolar structure laser diode driver IC that incorporates an APC circuit consisting of a reference voltage source and an error amplifier. The built-in reference voltage source stabilizes the laser output against changes in power supply voltage and temperature. It can drive laser currents of up to 400mA and achieves minimal footprint implementation in a compact SOT-26 package. Additionally, it features protection functions such as an abnormal high-temperature cutoff circuit, a laser drive current limiting function for control loop failures, and a built-in Zener diode for surge absorption to prevent laser diode destruction. In addition to APC control, it also allows for open-loop constant current driving using the built-in constant current setting function.
