Driver IC for automotive DC brushed motor

Toshiba Corporation launched TB9051FTG, P-QFN28 packaged 6mm × 6mm measuring motor driver IC for DC brushed motors used in automotive applications such as electronic throttle control, valve control, control of wing mirrors and trunk locks. "TB9051FTG" feature very low on-resistance due to the use of DMOS transistors as driver circuits. TB9051FTG features failure detection circuits for functional safety and built-in detection circuits include over current, over heat, low voltage and high voltage.
