Toshiba accelerates time to market for BLDC motor controls with Hall-effect sensing

Exploiting BiCMOS integration, the TB9067FNG simplifies design by integrating major functions such as three-phase commutation logic and gate-driver circuitry, a 5.12MHz oscillator, 5V regulator, and circuitry to detect system status. The device also provides selectable features including a choice of PWM-pulse or DC-level input control, and the option to run the motor from an external signal or using an internally generated PWM signal. An optional rapid startup mode is also available, which can be selected via external mode-control pins.

The motor and system errors detected by the TB9067FNG’s internal circuitry include over-current, over/under-voltage, and over-temperature of the IC or external driver MOSFETs. Over-current detection has two threshold levels for detecting motor-lock and short-circuits failures. In addition, selectable full-drive detection relieves the host system of the need to manage the output PWM duty cycle.

With junction operating temperature rated to 150°C, and meeting AEC-Q100, TS16949 and PPAP documentation requirements, the TB9067FNG satisfies automotive-industry requirements. It is ideal for brushed-motor replacement in pumping or motion-control applications. Its selectable modes and support for various input and output signal types also allows use as a slave in systems where one microcontroller is required to control multiple motors.
