Toshiba – ASIL-D compliant Motor Pre-Driver for Automotive Applications

Toshiba Electronics Europe (TEE) has announced a motor pre-driver IC for automotive applications such as electric power steering (EPS) systems where safety is of paramount importance. The TB9052FNG is suitable for use in systems adhering to ASIL-D, the highest automotive safety integrity level prescribed in functional safety standard ISO 26262.

In addition to the main pre-driver circuit, TB9052FNG incorporates various failure detection circuits for functional safety. Elements included are battery under voltage detection, over temperature and driver short detection circuits.

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 12.5×6.1×1.2mm. 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 start in March, 2015. Toshiba will also be supplying associated safety analysis documentation.

On request we will send you samples. The mass production will be at 2015.
