Toshiba launches sensorless control pre-driver for automotive applications

KUALA LUMPUR, March 28 (Bernama) -- Toshiba Electronic Devices & Storage Corporation (Toshiba) has launched a sensor-less control pre-driver IC ‘TB9062FNG’ for brushless DC motors (BLDC motors) used in automotive applications, including electric pumps.

Samples are available now while mass production is scheduled for December, according to a statement.

The new pre-driver can control BLDC motors by pulse-width modulation (PWM) input only, without a need for high-performance MCUs and software.

It has an automatic duty generation function that adjusts the output PWM duty cycle to suit the battery voltage (VBAT) at start-up, and a soft speed changing function that prevents stalls by suppressing sudden changes in output PWM duty.

The newly launched pre-driver also does not require any software development as it is controlled by a hard-wired logic circuit.

It has been implemented with VBAT over voltage detection, VBAT under voltage detection, over-current protection, and thermal shutdown circuits. The operating temperature range is -40°C to 125°C which is highly suited to automotive applications.

Toshiba is among the leading general device companies, offering customers and business partners outstanding solutions in discrete semiconductors, system LSIs and HDD. For more information, contact https://toshiba.semicon-storage.com.
