ML605 Hardware User Guide www.xilinx.com 75UG534 (v1.9) February 26, 2019Detailed DescriptionFan ControllerIn highly demanding situations, active thermal management in the form of a heat sink andfan may be required. In order to support this, drive circuitry for an external fan has beenprovided on the ML605. A fan with tach output can be connect at header J59 as shown inFigure 1-32. The fan PWM signal is generated by the FPGA and the tach input can be usedto close the control loop and regulate the fan speed. Alternatively, the FPGA temperatureas recorded by the System Monitor can be used to close the PWM control loop for the fan.X-Ref Target - Figure 1-32Figure 1-32: ML605 Fan Driver0VCC12_PVCC2V5123J592 1D161N4148R36710.0K1/16W1%1432Q24 NDT3055L1%1/16W10.0KR3681%4.75KR35812VGNDTach1%1/16W10.0KR369SM_FAN_PWMSM_FAN_TACHUG534_39 _081209Send Feedback
