Dual-Channel Laser Diode Driver with APC Amplifier for Multi-Beam Printers

FN6625 Rev 1.00 July 22, 2013
The ISL58125 is a high-performance dual channel laser driver that provides controlled current to grounded laser diodes. A bias current is summed with the switched current at the IOUT output, allowing the user to optimize laser diode performance.
Output switched current flows when the LVDS signal DATA is high. The output current returns to the fixed-threshold value when DATA is low. Complete IOUT shut-off is achieved by holding both of the DISx pins Hi, which will override all other control pins.
