The NJM3773FM2 is an integrated circuit designed for several different applications, ranging from audio output to motor drivers, controllers and voltage detection, making it an ideal choice for numerous circuits and projects. One of the primary applications for this IC is motor controllers, as it features an onboard PWM signal generator, an inverting amplifier, as well as a slew rate limited pulse amplifier. Additionally, the IC has been designed to support various power supplies and allows for a wide range of rated voltages.

The working principle of the NJM3773FM2 is fairly simple. The IC takes in a single-ended analog signal, either through a three-terminal voltage detection input or a PWM signal. It then uses an internal comparator and comparator reference to determine the output level, which is then pushed through a slew rate limited amplifier. The final output is then sent back out as either a voltage detection signal or a PWM signal depending on the chosen mode.

The NJM3773FM2 IC also includes several additional features, such as over-current protection, thermal shutdown protection, and an adjustable current limit. Additionally, the IC also supports an adjustable frequency control, which allows user to change the frequency of the PWM signal for better control over their circuits. This makes the NJM3773FM2 a great choice for motor control, as it allows for precise control over the speed and direction of the motor.

In terms of physical construction, the NJM3773FM2 is constructed out of a ceramic substrate, which serves as the core of the IC and contains all the features mentioned above. The substrate is then covered with a number of copper layers and adhesives, providing further protection and increased heat dissipation. The IC itself measures 9x19x4mm, allowing for a wide range of designs.

In conclusion, the NJM3773FM2 is an excellent choice for a wide range of problems involving motor control and voltage detection. Its ability to support a wide range of voltage sources, as well as its slew rate limited amplifier, make it ideal for both low-voltage and high-voltage control applications. Additionally, its over-current protection and adjustable current limit provide a significant safety layer, making it a reliable choice in many different circuit designs.
