DESCRIPTION

This laser driver is an electronic module designed for driving

diode lasers with up to 500mA constant current, high efficiency,

low noise, high reliability, zero EMI, and small package.

Figure 1 shows the photo of an actual ATLS500MA201D.

It provides these the functions: laser constant current control,

laser current monitoring, over current and thermal protection,

laser current control 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. The

reference output can also be used for the ADCs (Analog to

Digital Converters) and/or DACs (Digital to Analog

Converters).
