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.
