Toshiba Brushed Motor Pre-Driver IC Supports Advanced Safety Capabilities For Automotive Applications ASIL D compliant IC targets electric power steering, features failure detection
SAN JOSE, Calif., July 23, 2014 /PRNewswire/ -- Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced the TB9052FNG motor pre-driver IC. The new device was developed for safety-critical automotive applications such as electric power steering (EPS) and other systems compliant with Automotive Safety Integrity Level D (ASIL D), the most rigorous measure defined within functional safety standard ISO 26262.
"As electrical systems within vehicles become increasingly sophisticated, there is a concurrent need for components that support and enable the most advanced safety features," said Deepak Mithani, senior director, Mixed Signal Business Unit at TAEC. "Toshiba is committed to helping the automotive industry implement new safety measures by continuing to develop motor drivers that support these requirements."
In addition to the main pre-driver circuit, TB9052FNG features a built-in motor current detection circuit in a redundant configuration, reducing board size and system complexity while contributing to functional safety. Also contributing to functional safety are the product's range of circuits that detect system failures, including 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.
Sample shipments will start in August, with mass production scheduled to begin in March 2015. Toshiba will also be supplying associated safety analysis documentation.
