Brushless Motor Pre-Driver Targets Automotive EPS

Brushless Motor Pre-Driver Targets Automotive EPS
TOSHIBA AMERICA ELECTRONIC COMPONENTS INC.

Supporting functional safety requirements, the TB9081FG brushless motor pre-driver IC is ISO26262 ASIL-D compliant for use in electric power steering (EPS) systems. The IC integrates functions that include three-phase pre-driver circuits, fail-safe relay pre-driver circuits and motor current detection circuits, with a range of failure-detection circuits like VB over/under voltage detection, VCC over/under detection, over temperature detection, and short detection. The diagnostic circuit in the failure-detection circuit identifies any latent faults, while the fail-safe relay pre-driver circuits drive the semiconductor relay connections between the motor and MOSFET and between the power-supply side and MOSFET. Housed in a 12 mm x 12 mm x 1.6 mm LQFP64 package, the TB9081FG features 11 pre-driver channels and operates at 4.5V to 18V. Operating temperatures range from -40ºC to +125ºC. Sample shipments are under way and mass production is scheduled to start in August 2017.
