Laser Diode Driver ATLS2A201D with Constant Current

In the last article about 201 series laser drivers, we mentioned that the maximum current can be 1A, 2A, 3A, 4A and 6A. Therefore, this article is about 2A laser driver, ATLS2A201D. This laser driver has a high efficiency of ≥90% and a high stability of 100ppm/°C.

This laser driver will shut down when receiving one of the three signals, external shut down, over current and over temperature signals. Any of these signals is activated, the laser driver will shut down. Only if all the three signals go up, the laser driver can be turned on by a soft start circuit. This soft start circuit is inside the laser driver, which allows a slow start up and a quick shut down.

Another feature of this laser driver is loop good indication, which is indicated by LDGD pin. When this pin is >2V, the laser driver circuit is working well. If this pin is <0.3V, it indicates that there is a short or open circuit at the laser diode.
