The reference design combines Toshiba’s highly efficient low-voltage MOSFET devices with Toshiba’s dedicated motor control MCU and thus provides a very compact but flexible platform for the control and drive of BLDC motors in power tools. The Motor current is generated by a 3-phase inverter with 200W output power stage using the Toshiba TPH1R204PB low-voltage MOSFET. This device features industry-leading R_DS(ON) in a 5×6mm SOP Advanced package and provides low spike generation helping to prevent EMI effects. 

• Inverter for three 3-phase brushless DC motors, up to 750W each
• AGV moving with three omni wheels of 203mm diameter
• Line tracing through infrared sensor system

Toshiba’s TXZ+™ microcontroller takes performance to the next level. Complementary Toshiba original IP together with various useful peripheral functions add value for multi-axis motor control like AGVs and Servo Drives and data processing applications.

Morover system performance is increased and software development effort reduced. Manufactured in a modern 40nm CMOS process and equipped with 32-bit Arm® Cortex® processor cores the devices consume approximate 30% less power than Toshiba’s previous microcontroller generation.

Based on the company`s latest generation DMOS process, the TC78H660FNG driver can deliver a PWM-controlled current of 2A (maximum), meeting the modern requirements of mains, 5V USB and battery-powered equipment. Running off a 2.5V to 16V input supply voltage, it can drive two brushed DC motors or a single stepper motor

It comes with acompact 5.0mm x 6.4mm TSSOP16 package. Finally the TC78H660FNG driver is suitable for a broad spectrum of potential applications - such as mobile devices running off a 3.7V Li-Ion battery and 5V USB-powered equipment, as well as 12V-rated household appliances. 

The TC78B011FTG incorporates a sine-wave drive method reducing vibration and noise. Its sensorless design saves the space and cost of a Hall sensor and the built-in closed loop speed control regulates and maintains the motor’s rotational speed during dynamic power supply fluctuations and load variations without requiring an external microcontroller (MCU). The P-WQFN36-0505-0.50-001 package has a footprint of just 5mm x 5mm and a height of 0.8mm and is intended for a broad variety of consumer applications including 3D printers, cameras, security cameras, portable printers, handheld scanners, pico-projectors and battery powered medical devices.

The  TB67S539FTG extend the excellent lineup of Toshiba´s stepping motor driver ICs. Based upon Toshiba’s latest BiCD process, the device is capable of driving bipolar stepping motors at voltages up to 40V and currents up to 2.0A. The current detector is integrated within the QFN32 package (5.0mm x 5.0mm) and removes the need for an external current sense resistor. The device is suited for wide range of constant current control stepper motor applications (office automation, commercial and industrial equipment, plus surveillance cameras and projectors). 

Integrated DC motor drivers for automotive applications can be found in a variety of automotive application fields. Featuring a 1 channel H-Bridge with integrated MOSFETs, Toshiba’s TB9051FTG (MIKROE Clickboard^TM TB9051FTG) is able to drive up to 28V and 5A to the attached motor. It can be used e.g. inside an automotive grade door mirror, controlling the motorized fold and open of the mirror. Besides the device is also suitable for applications such as electronic throttle and valve control. It is AEC-Q100 qualified and uses various built-in failure detection features for functional safety. These include over current, over heat, low voltage and high voltage detection circuits. TB9051FTG offers  a compact P-QFN28 package (6mm × 6mm), well suited for small mounting boards.

Stepper Motor Driver Flyer

Qualified according to AEC-Q100 Grade 1, TB9053* and TB9054* (TB9053/54FTG Datasheet) integrate two separated 5A H-bridge channels to directly drive DC brushed motors. 10A 1-channel motor drive is possible when both channels are configured to operate in parallel. Motors can be controlled in real-time either by conventional PWM signals or by SPI, daisy-chain mode is also supported. The SPI interface is also used for advanced diagnosis as well as device parametrization.  Various failure detection mechanisms ensure a safe system operation.
