The Microchip 3 Phase Brushless Motor Gate Driver System Basis Chip (SBC) for brushless motor control, designed using advanced SOI technology. In combination with a microcontroller and six discrete power MOSFETs, the SBC forms a brushless DC motor control unit. Through six dedicated parallel inputs, the gate driver units (GDU) can be controlled independently, supporting duty cycle operations from 0% to 100%, due to the implementation of two charge pumps, for low and high-side gate drives. In addition, the circuit provides 5V and 3.3V low dropout voltage regulators, two current-sensing operational amplifiers, an integrated Back-EMF detection module and a window watchdog. The microcontroller controls the ATA6847 using an SPI interface.
