Chiplon Microelectronics has launched CLM5C711, a laser diode driver mainly used in laser printers and digital copiers, which includes laser power control function. The cathode of a 2ch laser diode (LD) and the anode of a monitoring photodiode (PD) are connected to the valve stem. After power activation, the first APC (Automatic Power Control) operation sets the driving current to the target LD intensity. There will be a dedicated interface between the CLM5C711 IC using two of the driving 4-beam semiconductor laser tube arrays (4ch LDA). This way, parallel APC and high-precision APC can be blocked by each LD. In addition, various fault safety functions have been enhanced to protect LD through error detection. This product directly Pin to Pin replaces similar international products without the need to change the circuit board or system software, achieving full compatibility and replacement. Chiplon Microelectronics has developed its own testing plan to ensure that the factory products meet or even exceed the original specifications, and support military grade (-40 ℃~125 ℃) working temperatures.
