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.

Power supply voltage range from 3V to 42V
Sleep deep sleep mode with maximum 15 μA current consumption with full wake-up capability local wake-up
3.3V or 5V microcontroller interface
Up to 4 MHz SPI bus for device configuration and register access
SPI frame error detection
Dedicated NIRQ pin for MCU external interrupt to report events directly
