PMIC - Laser Drivers

A MAX3723UTP+T is a type of laser driver, which can be classified as a Power Management and Interface Circuit (PMIC). This type of driver integrates an RF amplifier, a laser diode control circuit, and an optional thermistor interface, allowing the laser diode to operate in different modes, such as CW (1.8V) or Pulsed Mode (V < 1.8V).

The MAX3723UTP+T application field includes communications and storage applications, medical applications, sensing and metrology applications, fiber laser builds, and many smart power lasers. It is a programmable laser driver extended over the regular MAX3723UTP. It offers DC supply up to 8V, and up to 5.1V control voltage, as well as features that enable the user to operate mode control and laser diode current in both High Current and Low Current mode. The driver can also detect and report laser diode temperature.

The working principle of the MAX3723UTP+T is based on the main components which enable the laser diode to be connected and supplied with power. First of all, there is an RF amplifier circuit, in the form of an RF gate driver, which provides the voltage necessary for the laser diode to operate. Next, there is a Laser Diode control circuit, which provides control signals for regulating the laser diode current and temperature monitoring. Finally, an optional thermistor interface connects the laser diode and the MAX3723UTP+T in order to measure the laser diode temperature. With these components in place, the laser diode is capable of operating in both High Current and Low Current modes.

In summary, the MAX3723UTP+T is a type of PMIC that is specially designed to drive laser diodes in various applications. It has an RF amplifier, a laser diode control circuit, and an optional thermistor interface. This type of laser driver enables the user to control the operation of the laser diode in both High Current and Low Current mode, as well as providing temperature monitoring capabilities.
