ATA6847x 3-Phase Brushless DC (BLDC) Motor Gate Drivers

3-Phase Brushless Motor Gate Driver System Basis Chips (SBCs)

The ATA6847x family of 3-phase brushless motor gate driver SBCs is designed with advanced Silicon-on-Insulator (SOI) technology for brushless motor control. Available in both automotive and non-automotive versions and with functional safety support, these devices offer high integration for industrial, consumer and automotive applications. The ATA6847L variant’s built-in LIN transceiver streamlines your design by reducing the BOM and saving valuable PCB space. Delivering reliable, efficient and compact motor control the ATA6847x family helps you create smarter, faster and safer solutions.
