MTD6505 BLDC Fan Controller Demo Board

The MTD6505 3-Phase BLDC Sensorless Fan Controller Demonstration Board allows the control and monitoring of the MTD6505 device using PC software connected to the board via a USB connection. The included board software provides several features including VDD control and monitoring, pulse-width modulation (PWM) control, speed and current consumption monitoring. It also allows selecting the RPROG resistor value for fan fitting.

PIC24FJ256GB microcontroller for USB connection, PWM generation, FG frequency measurement, VDD measurement, other signal activation and component communication
Adjustable LDO (MCP1827) with a digital potentiometer (MCP42050) provide VDD to the MTD6505 device. The LDO can be enabled or disabled by the microcontroller
Digital potentiometer is also used to set the MTD6505 RPROG external resistor value
Delta-Sigma (MCP3421) ADC with a shunt resistor for sensing the MTD6505 current consumption on the VDD pin
4 x GUI-selectable KM ranges

Supplied with

3 x MTD6505 plug-in modules with soldered-on MTD6505 (3x3 UDFN-10L), USB cable, 3-Phase BLDC fan (use with KM=1, Important Information Sheet
