Toshiba launches ic for BLDC pump motor control

Targeted at automotive applications such as BLDC pump motor control, the TB9061AFNG from Toshiba Electronics Europe is a three phase, brushless, sensorless motor controller ic with integrated pre-drivers.

The device enables cars equipped with an idling reduction system cut out to easily switch the power source for oil and engine cooling pumps from the engine to an electric motor when the system is activated. The TB9061AFNG is rated for use over -40 to 125°C, making it suitable for use in very hot environments, such as those found in automotive engine compartments. Traditionally, motor drivers use external Hall sensors to detect rotary position and rotation speed. In contrast, Toshiba's brushless motor drive ic is designed to achieve 120° rectangular wave motor control by using an input signal line that measures the induced voltage of the motors and three phase motor output without using Hall sensors. Toshiba claims the device enables simple system configuration and smaller pcb size, contributing to material and system cost reductions. Motor rotation can be controlled by either the dc input signal or the pwm input signal.
