PMICs, or power management integrated circuits, are designed to regulate, monitor, and convert electrical power efficiently while keeping power losses as low as possible. Within the realm of PMICs are specialized devices known as Laser Drivers. These are specifically designed to control lasers efficiently while preventing dangerous amounts of power from going out. A leading example of laser drivers is the NT22L31-A06-QFN-TR. This device belongs to the family of low-capacitance transient voltage suppressor (TVS) array products from ON Semiconductor.

The NT22L31-A06-QFN-TR is a laser driver that helps to mitigate transient or external events which could affect the function or lifetime of the laser diode. This type of device is at the core of many applications in the medial device and life sciences industry, as well as many other industries involving the integration of lasers. As for the industry, it is used most commonly in general-purpose or specialty laser diodes such as high-power, pulsed, broadband, semiconductor-based diode lasers, laser diode modules, as well as infrared and visible lasers.

In terms of core principles, the NT22L31-A06-QFN-TR is designed to prevent the laser diode from being exposed to overvoltage. It helps maintain laser diode output power and power stability by matching the threshold voltage to the forward voltage of the laser diode. While this goes over the head of the common consumer, it is the basic working principle of a laser driver nonetheless. This device also provides laser diode protection against reversed-bias events.

The NT22L31-A06-QFN-TR also provides a wide range of protection against overheating, as it gives thermal shutdown protection to the laser diode. This device keeps the laser diode functioning within its own safe operating temperature range by sensing the temperature of the laser diode and automatically cutting off power supply when the temperature gets too high. As such, the device itself is able to provide fast and accurate thermal protection for the laser diode.

The device also helps protect the laser diode against electrical surges, particularly those of electrostatic discharge (ESD) events. This helps reduce the risk of damage to the laser diode during manufacturing, as well as when the laser diode is being handled. The device has an ESD rating of ± 8 kV per HBM.

On the manufacturing side, the NT22L31-A06-QFN-TR is designed in a compact 8-terminal, low-profile package with an operating temperature range of -50˚C to +150˚C. This makes it easier to produce and more cost-effective in the long run. Another bonus is that it is halogen-free, making it a safe choice for environmentally conscious factories and laboratories looking to reduce their carbon footprint.

The NT22L31-A06-QFN-TR offers a great performance-to-cost ratio and is well-suited for integrated laser systems, communication systems, and high-power pulsed laser systems. Its robust design, efficient power savings, and great protection features for the laser diode make it an attractive choice for many different industries.
