ATI ATLS3A201D

This laser driver is an electronic module specifically designed to drive diode lasers at a constant current of 3A. It features high efficiency, low noise, high reliability, EMI shielding, and a compact form factor. It provides the following functions: laser constant current control, laser current monitoring, overcurrent and over-temperature protection, laser current control indication, laser diode status indication, soft start and shutdown. It incorporates a highly stable, low-noise 2.5V reference voltage. The output current can be set by adjusting the voltage on the LIS pin via a potentiometer or DAC. An ADC can also be connected to monitor the output current by measuring the voltage on the LIO pin. The ATLS3A201D is housed in a six-sided metal enclosure that shields against EMI, preventing mutual interference between the driver and other electronic components.
