Product Overview:

High Voltage, Compact, OEM Laser Diode Driver Overview

The ATLS100MA116D is an electronic module designed for driving diode lasers with up to 100mA low noise current.

In order to maximize electrical and thermal efficiency, the maximum output voltage of the driver is 2V less than the input voltage. This feature allows the designer to tailor the system to the exact laser specifications, and maximizes overall system efficiency.

Maximum Stability in Real-World Environments

The controller has a temperature compensation network so that the output current remains the same even as the controller temperature rises. In case the controller temperature exceeds the preset limit of 120°C, the controller will shut down by itself to prevent being damaged by high temperature.

When the maximum power consumed by the controller is maintained to <1W, it does not require a heat sink to operate.

Laser Diode Protection Features

The laser driver includes three safety shut-down modes: external shut down, output current exceeds the current limit, and the internal temperature exceeds 120°C. These shut-down modes protect the laser diode from damage over a wide range of operating errors, and help maintain the overall integrity of the laser system.

Design and Application Flexibility

The output current of the ATLS100MA116D can be set by an input voltage linearly, or modulated by an external large signal of up to 1MHz in bandwidth, resulting in a minimum 170nS rise and fall time (large signal) at the output current.

A highly stable low noise 2.5V reference voltage is provided internally for setting the output current. This reference can also be used as the voltage reference for external ADCs (Analog to Digital Converters) and/or DACs (Digital to Analog Converters) which are utilized for converting the analog signals, such as LIO which represents the output current, into digital signals, and/or converting the digital signals for setting the analog voltages, such as LIS which sets the output current.

The ATLS100MA116D is packaged in a 6-sided metal enclosure which blocks EMI (Electro-Magnetic Interference) to prevent the controller and other electronics from interfering with each other.
