It accepts a 3V to 5.5V supply and communicates via a parallel interface, making it a straightforward drop-in for designs that need closed-loop fan speed regulation without a separate microcontroller. The pre-driver output drives external N-channel MOSFETs on the low side of the BLDC motor phases, so the actual motor current rating is set by the external FETs and thermal management, not by the controller itself. This gives the layout engineer flexibility to scale the fan power stage independently of the control logic. ## Supply voltage and temperature envelope The 8-SOIC package (0.154\" body width, 3.90 mm) is a standard footprint with a 1.27 mm pitch, so the PCB layout matches any generic SOIC-8 land pattern. The supplier device package is listed as 8-SOIC, confirming the same mechanical outline. ## Lifecycle and sourcing posture for the TC648VOA713 The part is ROHS3 compliant, so it clears the material-restriction requirement for most commercial and industrial BOMs without an exemption review.","metaTitle":"Microchip TC648VOA713 BLDC Fan Speed Controller, 8-SOIC","metaDescription":"Active Microchip TC648VOA713 fan speed controller for BLDC motors. 3V-5.5V supply, parallel interface, 8-SOIC package.
