Frequently Asked Questions and Answers.

1. Q: How to use the current limit and current setting functions of ATLSxA103?
A: Both LIS and LILM sets the output current of laser driver ATLSxA103. The former sets the output current precisely and enables the drive to output a low noise current which can be modulated by high speed analog signal. The latter, LILM, can protect the laser from being damaged by an over current accidently caused by an over voltage applied on the LIS pin. When the current limit function set by LILM pin is activated, the laser driver is shut down, wait for a while, then the laser driver is turned back on. If the current still exceeds the limit, the laser driver will be turned on again. This cycle will repeat till the over current stops.
