MAX3668EHJ+T is a laser driver developed by Maxim Integrated that is designed for use in high performance and flexibility applications. The IC offers various configurations for the laser source and for temporal modulation. The device can be used for range finding and distance measurement applications, automotive safety, industrial safety, high speed imaging, and other imaging systems. In addition, the device can be used in laser scanners, spectrometers, 3D imaging, and other machine vision applications.

The core component of the MAX3668EHJ+T is a two-channel laser driver that is capable of driving two laser diodes in either series or parallel. The two channels are each capable of providing 0.45A (maximum) of current and can be enabled or disabled by an Enable/Disable input pin. Each channel also has two stabilization elements that help to reduce any unwanted oscillations or noises generated by the laser diodes. In addition, the device can support up to four synchronous or asynchronous TTL input pulses, allowing for time controlled pulsed or pulse-width modulation (PWM) of the laser current.

The MAX3668EHJ+T is designed to operate in an ambient temperature range of -40ºC to +105ºC, making it suitable for use in industrial and medical applications requiring a wide operating temperature range. The device also has a maximum power dissipation of 3W, and a maximum power consumption of 1.2W, making it a very efficient driver.

The main purpose of the MAX3668EHJ+T is to provide a high efficiency, high frequency, and low noise solution for driving high power laser diodes. This device is ideal for applications requiring high speed, high precision, and high reliability, such as range finding and distance measurement applications, high speed imaging, and other machine vision applications. The device is also suitable for Pulse Width Modulation (PWM) applications such as laser scanning, spectro-imaging and 3D imaging.

The MAX3668EHJ+T is based on a high-current, low-noise, high-efficiency switching architecture that allows faster rise and fall times and supports a wide variety of laser configurations. The device also utilizes a low-noise totem pole output for fast switching and a high-side N-Channel FET switch between the output and the laser diode for increased safety and efficiency. Other features of the device include built-in thermal shutdown, under-voltage lockout, and over voltage protection, as well as a remote-sense output that can compensate for VCC variations.

It is of paramount importance that users of the MAX3668EHJ+T be aware of the potentially dangerous laser diodes so that proper safety precautions can be taken to ensure the safety of those using the device. The laser diode must be isolated from the body and external influences, and shielded sufficiently such that any stray laser radiation does not escape. Users should also be aware of the various regulations and standards for laser safety for their specific application.

In conclusion, the MAX3668EHJ+T is a high-performance, ultra-efficient laser driver from Maxim Integrated that can be used in a wide range of applications requiring high performance and flexibility. The device is specifically designed to drive high-power laser diodes with a wide range of power, current, and modulation capabilities. The device is also highly reliable, efficient, and comes with safety features that ensure the user’s safety. For these reasons, the MAX3668EHJ+T is an excellent choice for any application that requires reliable, accurate and efficient laser driving.
