DM7316G-65517-B1 is a 4-channel Type 2 monolithic linear fan-controller for CPU cooler applications. It provides a four-channel system for controlling the speed and current of fan motors independently. The device uses through-hole mounting and measures just 11mm x 11mm x 12mm. The controller is designed to have a very fast response time, which allows it to detect and control fan speed changes quickly and accurately. This controller supports both DC and PWM modes.

The four channels of the DM7316G-65517-B1 provide separate speed and current control for each fan. The four channels are visually divided into two sets of two channels, each set having one channel for speed and one for current control. A signal-processing circuit is used to detect and differentiate fan speed and provide a signal to the set of channels for speed control.

The speed control channels of the DM7316G-65517-B1 use a closed loop architecture, where the input to the speed control channels is a voltage signal from the fan. This signal is processed and compared with a reference voltage. The error signal derived from the comparison is then used to adjust the output voltage level to maintain the fan\'s speed. The output voltage is adjustable using a potentiometer, allowing the user to easily adjust the fan speed.

The current control channels of the DM7316G-65517-B1 use open loop architecture. The input to the current control channels is the output current from the fan. This current is monitored and, if the preset maximum current level is exceeded, then the output voltage is reduced to prevent damage to the fan motors.

The DM7316G-65517-B1 is designed to be flexible and easy to use. It has an operating temperature of -20°C to +85°C and a supply voltage of 3.3V to 20V. This makes it suitable for most fan applications. The controller is also RoHS compliant, making it safe and reliable for use in environmental applications.

The main application of the DM7316G-65517-B1 is to control the fan speed and current of CPU cooler applications. It is also suitable for controlling other types of fans, such as radiator or case fans. The device is an ideal solution for ensuring reliable and efficient cooling of electronic systems, while providing flexibility and easy adjustment of fan speeds.

In conclusion, the DM7316G-65517-B1 is a 4-channel Type 2 monolithic linear fan-controller designed to provide reliable cooling in CPU cooler applications. It has a fast response time, allowing it to detect and control fan speed changes quickly and accurately. It supports both DC and PWM modes, providing flexibility and easy adjustment of fan speeds. The device is RoHS compliant, making it safe and reliable for use in environmental applications.
