Toshiba Electronics Europe has expanded its range of motor pre-driver ICs with a device optimised for brushless DC motors with Hall-effect position sensing.

The TB9067FNG integrates 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 start up 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.
