Automotive cooling fan based on Microchip dsPIC33CDVL64MC106

The Micochip Automotive Cooling Fan Solution is designed to drive a three-phase permanent magnet synchronous or brushless DC automotive cooling fan motor that can be networked via LIN. The design is based on Microchip's motor control system-in-package (SiP) dsPIC33CDVL64MC106.

The SiP includes the dsPIC33CK64MC105 DSC, the MCP8021 three-phase MOSFET gate driver with LDO, and the ATA663211 LIN transceiver. For detailed design, please download the attached "Automotive Cooling Solution Reference Design User Guide".
