It integrates a pre-driver low-side output stage that drives external N-channel MOSFETs, so the actual power handling is set by the external FETs and the thermal design of the board, not by the controller itself. ## I²C interface and output drive Speed control is set through the I²C bus — the controller reads the target RPM from the bus and adjusts the drive PWM to the external low-side FETs. The pre-driver output configuration means the controller handles the gate drive logic while the external MOSFETs switch the fan current, keeping the heat out of the controller package. The 10-uMAX/uSOP package (3.00 mm × 3.00 mm body, 0.118-inch pitch) is a compact surface-mount footprint that fits on the control side of a power supply PCB without consuming board area that belongs to the power stage.","metaTitle":"MAX6650EUB+ Analog Devices BLDC Fan Controller, I²C, 10-uMAX","metaDescription":"MAX6650EUB+ from Analog Devices: brushless DC fan speed controller, I²C interface, 3V-5.5V supply, 10-uMAX package.
