MCZ33903CD3EK is a voltage-mode fan-speed controller designed particularly for the automotive market. It is designed to drive fractional horsepower brushless DC fans operating at up to 17W and 6V, and offers extreme precision, adjustable speed range as well as a variety of safety features and power management.

MCZ33903CD3EK is a special interface featuring a voltage-mode fan-speed controller to manage fan speed for automotive application. It provides a regulated low-side and high-side drive for the fans, so that the speed controlled by the voltage applied is transferred from the controller. The controller contains a voltage control module, which can accept a DC input voltage and then control the fan according to the set speed that has been previously defined.

The voltage control module consists of an adjustable high-side and low-side drive, two error amplifiers, an on-board reference voltage, an adjustable clock oscillator, an adjustable output boundary, and a comparator. The high-side and low-side drives can be adjusted in terms to provide an optimal speed range for the fan. The adjustable output boundary ensures that the final output is within a certain range and the adjustable clock oscillator provides the maximum resolution of the fan\'s speed.

The MCZ33903CD3EK offers superior precision, a robust package, and a wide range of features to ensure reliable operation in extreme conditions. It is ideal for harsh and extreme conditions such as engines and transmissions, where accuracy and reliability are critical. In addition to maintaining fan speed, the controller offers a range of safety features such as over-voltage protection, under-voltage protection, overload protection, and thermal protection.

The controller also features a power management module that is designed to provide additional safety and reliability. The power management module monitors the current draw when the fan is in operation and will shut down the fan when the current draw exceeds its capacity. This ensures that the fan is not over-loaded, resulting in cooling system failure.

The MCZ33903CD3EK provides a wide range of features to meet the demanding requirements of automotive applications. It is designed to provide superior performance and reliable operation in severe conditions. With its adjustable voltage range and adjustable clock speed, the controller offers precise control of fan speeds. The controller is capable of controlling fans with higher power requirements, and it offers additional safety features such as over-current protection, over-temperature protection, and adjustable voltage output.

The MCZ33903CD3EK is an excellent choice for automotive fan-speed control applications. With its wide range of features, robust package, and enhanced safety features, the controller provides superior performance and reliability in extreme conditions. The controller is also ideal for other applications requiring precise fan speed control, such as air flow control and industrial fan control.
