The TB9052FNG incorporates the main pre-driver circuit plus various failure detection circuits for functional safety. Elements included are battery under voltage detection, over temperature and driver short detection circuits.
The IC has four channels: two high side and two low side, and includes a charge pump to solely drive N-channel MOSFETs. It comes 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.
