Toshiba Launches Sensorless Control Pre-Driver IC for Automotive BLDC Motors

TOKYO — (BUSINESS WIRE) — March 27, 2019Toshiba Electronic Devices & Storage Corporation (“Toshiba”) today announced the launch of a sensorless control pre-driver IC “TB9062FNG” for brushless DC motors (BLDC motors) used in automotive applications, including electric pumps. Samples are available now, with mass production scheduled for December this year.

The new pre-driver can control BLDC motors by pulse-width modulation (PWM) input[1] only, without any need for high-performance MCUs and software.

TB9062FNG has an automatic duty generation function that adjusts the output PWM duty cycle to suit the battery voltage (VBAT) at startup, and a soft speed changing function that prevents stalls by suppressing sudden changes in output PWM duty. These functions, which were absent from Toshiba’s earlier products, contribute to stable motor control.

TB9062FNG does not require any software development as it is controlled by a hard-wired logic circuit. VBAT over voltage detection, VBAT under voltage detection, over current protection, and thermal shutdown circuits are also implemented. The operating temperature range is -40°C to 125°C, highly suited to automotive applications.
