Power management integrated circuits (PMICs) characterized by motor drivers, controllers, and other functional applications, are a critical part of embedded systems such as wearables, robotics, medical devices, and the automotive industry. TB67B008FTG is a motor driver IC manufactured by Toshiba specifically designed for automotive, industrial, and consumer applications, with a particular emphasis on driving stepper motors.

Features & Specifications

This motor driver IC includes a wide range of features that makes it ideal for use in a variety of applications. It is a three-phase full-bridge driver with two input channels, each capable of carrying up to 2000 mA. The device features slew rate control and low-side overcurrent protection. Additionally, the package is offered in both standard and high voltage options. The device has a maximum output voltage of +30V and a minimum output voltage of -15V.

The device also features a built-in automatic idle current reduction feature. This feature reduces the current consumption of the device when it is not being used, thus providing improved power efficiency and making it suitable for battery powered applications. The device also includes a thermal shutdown function which disables the device if it exceeds a certain temperature threshold.

The device is relatively small, measuring only 12.6 x 4.6 mm, making it ideal for use in space-constrained applications. Furthermore, the device is housed in a plastic package and can operate at temperatures between -40°C and +125°C.

Applications

The TB67B008FTG motor driver IC is ideally suited for driving stepper motors in automotive applications such as window lifts, power seat motors, or throttle control. It can also be used in lead screw or belt drive applications such as CNC machines. It is also ideal for applications such as robotics, measuring instruments, and retail And POS terminals.

Working Principle

The TB67B008FTG is an H-bridge driver IC, meaning that it controls the current flow between two inputs, in this case the motor coil ends. When the device is powered up, the voltage is applied across the two inputs causing a current to flow between them.

The IC enables the motor to be powered in both directions depending on the configuration of the input signals. The IC uses P-channel and N-channel MOSFETS for the high and low side, respectively. When a logic 0 is applied to the appropriate input pin, the device will turn on the MOSFET, thus allowing current to flow in the desired direction. Conversely, when a logic 1 is applied to an input pin, the device will turn off the MOSFET allowing the circuit to be powered in the opposite direction.

The IC also includes two sets of current sense resistors which can be used to measure the current in the motor and to detect overcurrent faults. The device can be programmed to terminate the current flow to the motor if the current exceeds a certain pre-defined value.

Conclusion

The TB67B008FTG is a motor driver IC designed specifically by Toshiba for automotive, industrial, and consumer applications. While primarily intended for driving stepper motors, it can also be used in lead screw or belt drive applications. It has a wide range of features that makes it ideal for battery powered applications, and can operate temperatures between -40°C and +125°C. It is also relatively compact, measuring only 12.6 x 4.6 mm, and is housed in a plastic package.
