About This Product

■BLDC motor flash MCU and driver

BD66FM8345C is a high-performance RISC architecture microcontroller with 8-bit flash memory and three half-bridge driver circuit groups for directly driving brushless DC motors and a fully integrated circuit specifically designed for brushless DC motor applications. It has many special features. Regarding memory functionality, flash memory provides users with the convenience of multiprogramming capabilities. Other memory includes areas of RAM data memory. Using application programming technology, users have a convenient way to save measurement data directly to flash program memory, as well as easily update application programs. In addition to the benefits of low power consumption and I/O flexibility, the device includes multiple highly flexible timer modules, an internal oscillator, a multichannel A/D converter, a D/A converter, operational amplifiers, and pulse width modulation capabilities. , 16-bit capture timer module function, comparator, motor protection module, Hall sensor position detection function, UART interface function, 16-bit MDU, time base function, 5VLDO, low voltage reset, low voltage detection, power down and wake up function as well. Included. This device integrates a high voltage FG output. Specifically designed for brushless DC motor applications, the device's enhanced versatility allows it to be used in a wide range of electrical tool applications, including upright fans, cooling fans, and air purifiers.
