Motor pre-driver IC for power steering in cars
Toshiba's new TB9052FNG motor pre-driver IC is designed for electric power steering (EPS) and other systems compliant with Automotive Safety Integrity Level D (ASIL D).
TB9052FNG has built-in motor current detection circuit in a redundant configuration and has circuits to detect battery under-voltage, 5V under voltage, over temperature and driver electrical short.
The TB9052FNG pre-driver IC has four channels, two high-side and two low-side, and includes a charge pump to solely drive N-channel MOSFETs. It is contained in a HTSSOP48-P-300-0.50 package measuring 12.5 x 6.1 x 1.2mm. Operating voltage range is +6 to 18V and operating temperature range is from -40 to +125 degrees C.
Availability: Sample shipments will start in August, with mass production scheduled to begin in March 2015.
