Toshiba TB9083FTG pre-driver IC for automotive applications
Toshiba Electronic Devices & Storage has developed the TB9083FTG, a pre-driver IC for automotive applications including brushless motors for electric power steering systems and electric brakes.
The three-phase pre-driver controls and drives external N-channel power MOSFETs for driving a three-phase brushless DC motor. It supports ASIL-D functional safety and its compliance with ISO 26262 2nd edition allows for use in highly safety-critical automotive systems.
The 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.
The product is housed in a small P-VQFN48-0707-0.50-005 package (7 x 7 mm typ) with a wettable flank structure. As the need for redundant design imposes restrictions on electronic control unit board area, adoption of this small package helps to reduce the total mounting area.
