A laser driver is an electronic circuit used to drive a laser diode. It usually comprises of a power supply and some form of current control, such as adjustable current limited circuits. Laser drivers enable precise control of the laser diode’s output power, ensuring that delicate and powerful lasers are not damaged or overdriven.

The MAX3656ETG is a high-performance, integrated laser driver designed to enable the most efficient laser diode operation in a variety of applications. It is a low-power, low-noise laser diode driver that features high efficiency, low output capacitance, and fast transient response that are critical for efficient laser operation.

The MAX3656ETG has two output channels and each of them can be configured to deliver up to 20A of current. The output power can be adjusted over a wide range by using the onboard multi-stage looped control. This allows for precise control over the laser power and helps with the stability of the laser operation.

The MAX3656ETG can make use of either an external or integrated voltage reference. It also includes a wide range of safety monitoring features, including overcurrent, short circuit, and voltage protection. This makes it much safer to use than traditional laser drivers that lack these features.

The MAX3656ETG is suitable for many applications, including Light Detection and Ranging (LIDAR) systems, laser range finders, LiDAR measurement systems, laser-illuminated light displays, and other laser applications. It is also suitable for the biometric sensing applications where high levels of precision are required.

The working principle of the MAX3656ETG is simple. It first detects the output current and then adjusts the output voltage as needed to keep the current at the desired level. This approach ensures that the laser diode is not damaged or overdriven, while also enabling precise control of the laser output.

The MAX3656ETG offers many advantages over traditional laser drivers. It is much more efficient, has a faster transient response, and requires less power. It also has better control and overall stability, which is critical in many laser applications. All of these features make the MAX3656ETG an ideal choice for a variety of laser applications.
