Introduction: SY88922VKG-TR is a versatile power management integrated circuit (PMIC) designed by Semtech. It belongs to the Laser Drivers or LDs product category and provides a highly integrated, cost effective solution for controlling the high current laser driver sourcing. This part is designed to be used in industrial applications such as machine vision, food inspection, medical diagnostics, imaging, digital printing and other high precision machine applications.
Application Field: SY88922VKG-TR has the capability to directly drive lasers from 200mA to 4A pulsed peak current, controlling the electrical current and high-speed switching at the same time. It is specifically designed for industrial applications requiring high current capability, accuracy and excellent regulation stability. Since it is compatible with a wide range of smartphone applications such as image capture, video capture and recording, the SY88922VKG-TR is ideal for automotive, wearables, and other electronic products in need of high performance laser drivers.
Working Principle: SY88922VKG-TR utilizes pulse width modulation (PWM) to control the laser driver. When the PWM signal is applied to the input, SY88922VKG-TR converts it into a high precision regulated 0-4A current, the output current is coupled to the LED driver’s base. The laser output power will then be regulated via the amplifier and current sensing resistor. Additionally, in order to avoid any risk of external overvoltage, SY88922VKG-TR provides transient protection of up to 90V.
Aside from providing drivers and low-noise circuits, the SY88922VKG-TR also features adjustable voltage feedback, which allows the user to adjust the load current regulation level for more precise control. It features both open loop and closed loop control modes that are ideal for controlling the laser power. Furthermore, the SY88922VKG-TR includes a low-ripple VCCX supply and low-noise linear regulators that provide improved stability, increased efficiency and reduced chip area.
The SY88922VKG-TR part also includes an advanced high slew-rate switching controller with an integrated automatic fault protection (AFP) circuit. The AFP circuit is specially designed to shut off the switch in the presence of an over current protection (OCP), over voltage protection (OVP) or over temperature protection (OTP) event. In addition, the part also offers overshoot protection and watchdog functionality to help ensure that the part is operating correctly and within the prescribed safety limits.
The SY88922VKG-TR has also integrated a high accuracy output current amplifier that helps maintain the laser’s power characteristics. This amplifier allows the user to finely adjust the output current with up to 0.5% accuracy, while adjusting the voltage feedback can help to compensate for temperature changes and other fluctuations. The SY88922VKG-TR also includes an unlock pin, which when pulled low, will disable the power switch protection, allowing the user to shut off the power switch when the laser is not in use.
Conclusion: In summary, the SY88922VKG-TR is an ideal laser driver for industrial applications, featuring excellent regulation stability and accuracy, and is designed to directly drive lasers from 200mA to 4A pulsed peak current. It is also equipped with several protection mechanisms and a high accuracy output current amplifier that can help to regulate the laser power with excellent accuracy.
