Toshiba Launches 3 Phase Brushless Sensorless Motor Pre-Driver IC – Sep 27, 2013– Tokyo, Japan (Techreleased) – Toshiba Corporation today announced that it has launched a 3-phase brushless[1] sensorless motor[2] pre-driver IC for automotive applications, “TB9061AFNG”. Sample shipments will start in October, with mass production scheduled to start in March, 2014.
TB9061AFNG
The engines of cars equipped with an idling reduction system cut out when the system is activated, and the power source for oil pumps and engine cooling pumps must be shifted from the engine to the motor. The new IC incorporates Toshiba’s original brushless motor drive control circuit that can control motors without using heat-sensitive hole sensors[3], securing control of pumps in a very hot environment. The product also contributes to materials and cost reductions.
