DESCRIPTION

This laser driver, ATLS6A201D, is an electronic module

designed for driving diode lasers by up to 6A constant

current with high efficiency, low noise, high reliability, zero

EMI, and small package. There are two types:

ATLS6A201D and ATLS6A201D-PD, and the latter has a

pull-down resistor to the ground. Figure 1.1 shows physical

photo of the ATLS6A201D and Figure 1.2 shows the photo

of ATLS6A201D-PD.

It provides these functions: laser current control, laser

current monitoring, over temperature protection, loop good

indication, laser diode status indication, soft start, and shut

down.

It comes with a high stability low noise 2.5V voltage

reference output which can be used for setting the output

current and, at the same time, for the ADCs (Analog to

Digital Converters) and/or DACs (Digital to Analog

Converters) as the reference voltage.
