Toshiba Starts Sample Shipments of Pre-Driver IC for Automotive Brushless Motors Supporting Functional Safety

Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has begun shipping test samples of “TB9083FTG,” a pre-driver IC for automotive applications that include brushless motors for electric power steering systems and electric brakes.
Toshiba will ship final samples in January 2022, and will start mass production in December 2022.

TB9083FTG is a three-phase pre-driver that controls and drives external N-channel power MOSFETs for driving a three-phase brushless DC motor. It supports ASIL-D[1] functional safety[2] and its compliance with ISO 26262 2nd edition allows use in for highly safety-critical automotive systems.

The new IC has a built-in three-channel pre-driver for the safety relays that control and drive the relays for motors and power supply. This eliminates the need for external components and helps reduce the part count.

TB9083FTG is housed in a small P-VQFN48-0707-0.50-005 package (7.0mm x 7.0mm (typ.)) with a wettable flank[3] structure. As the need for redundant design imposes restrictions on electronic control unit board area, adoption of this small packages helps to reduce the total mounting area.”
