NCP163AFCS250T2G

The NCP163AFCS250T2G is a linear voltage regulator designed as a fan motor control IC in a two-pin, surface-mount package. It is used for controlling the operating voltage of a fan motor in applications such as server cooling systems, computer systems, and desktop computers. The NCP163AFCS250T2G has a fast transient response, allowing the fan to quickly reach the desired voltage levels, making it suitable for applications in which rapid changes in speed and in current are needed.

At the heart of the NCP163AFCS250T2G is a precision voltage reference, which is used to set the operating voltage of the fan motor. The output voltage is selected by connecting the appropriate pins with a voltage setting resistor (RS). The fan motor is then connected to the output, and it will operate at the selected voltage. The precision reference, coupled with the low output impedance, ensure that the output voltage is maintained even when the load changes.

To provide a high degree of protection, the NCP163AFCS250T2G provides over-current protection, over-voltage protection, and reverse polarity protection. Over-current protection prevents damage to the fan motor due to excessive current, and over-voltage protection prevents damage to the fan motor due to an over-voltage condition. The reverse polarity protection ensures that the fan motor is not damaged in the event of an incorrect connection.

In addition to the protection features, the NCP163AFCS250T2G also provides a direction pin, which can be used to switch the fan motor in either direction. This feature can be used in applications where the fan is controlled by a single control line and it is necessary to change the fan direction.

The NCP163AFCS250T2G linear voltage regulator is suitable for applications where a high degree of protection is desired, and where a rapid response time is needed. The fan motor can be controlled easily and quickly, allowing the system to maintain its desired voltage level, and preventing damage to the fan motor.
