PMIC, short for Power Management IC, is an integrated circuit designed to control the power supply of an electronic device by controlling the voltage and current output of a specific power source. Laser Drivers, as part of PMIC, are designed to monitor and control the amount of current flowing to a laser diode, either in the visible or invisible spectrum.The ADN2870ACPZ-RL, a high-speed, high-performance laser diode driver, is a type of Laser Driver. It provides the high speed, low jitter and high resolution required for telecommunication systems, fiber optic sensing and laser control applications. The device operates from a single supply and integrates a high-side current source with a low-side sink.The application field of the ADN2870ACPZ-RL comprises active and passive optical components, high-speed signaling and data transmission, optical amplifier control in telecom, sensing, instrumentation, broadcasting and automotive applications. It is suitable for the generation and control of multiple laser wavelengths, including 1310nm and 1550nm wavelengths.The working principle of the ADN2870ACPZ-RL relies on its built-in features making it a very precise, precise and suitable device for various applications. To monitor and control the current flowing to a laser diode, the driver is designed with a current mode topology consisting of an adjustable high-side current source, a low-side sink current protection and a digital control module.The high-side current source allows the user to inject their desired amount of current into the laser diode with a voltage of up to 12V. This allows for precise and stable control of the amount of current to the laser diode. Further, the low-side sink current protection monitors and ensures that not too much current is let out.The digital control part adds the required intelligence for controlling the device, such as the regulation of the output current or the monitoring of the laser\'s power. Additionally, the ADN2870ACPZ-RL includes a programmable laser current detection window, which ensures accurate operations in case of an overcurrent situation.In conclusion, the ADN2870ACPZ-RL is a useful and accurate device that provides precise control of the current to the laser diode. With its adjustable high-side current source, low-side sink current protection, digital control module and programmable laser current detection window, it is suitable for many telecom, sensing, instrumentation, broadcasting and automotive applications.
