TB6556FG is a 3-phase full-wave sine-wave PWM brushless motor controller. It features sine-wave PWM control and includes a built-in triangular-wave generator with a carrier cycle defined as fosc/252 (Hz). The device also offers a built-in lead angle control function that can be adjusted from 0 to 58 degrees in 32 steps, with options for both external and automatic internal settings. Additionally, it incorporates a built-in dead time function that can be set to either 2.6 µs or 3.8 µs. The controller is equipped with an overcurrent protection signal input pin and a built-in regulator that outputs Vrefout at 5 V (typical) with a maximum current of 30 mA. The operating supply voltage range for the TB6556FG is from 6 V to 10 V, and it is produced by Toshiba Semiconductor.

The TB6556FG is designed for efficient control of brushless DC motors, leveraging advanced PWM techniques to ensure smooth operation and precise control over motor speed and torque. The sine-wave PWM control method minimizes harmonic distortion and reduces acoustic noise, making it ideal for applications where quiet operation is essential. The built-in triangular-wave generator provides a stable reference for the PWM modulation, ensuring consistent performance across varying load conditions.

The lead angle control feature is critical for optimizing motor performance, allowing users to adjust the phase relationship between the current and back EMF of the motor. This adjustment aids in improving efficiency and responsiveness, particularly in dynamic applications. The option for both external and automatic internal settings provides flexibility for different design requirements.

Dead time control is an essential aspect of motor control, as it prevents shoot-through conditions in the power stage, enhancing reliability and safety. The selectable dead time of 2.6 µs or 3.8 µs allows for customization based on the specific characteristics of the power transistors used in the circuit.

The overcurrent protection mechanism is vital for safeguarding the motor and the driver circuitry from potential damage due to excessive current conditions. This feature enhances the robustness of the design, ensuring longevity and reliability in various operational scenarios.

The integrated voltage regulator simplifies the design process by providing a stable reference voltage for other components in the system. With an output of 5 V and a maximum current capability of 30 mA, it can power small logic circuits or sensors that may be part of the motor control system.

Operating within a voltage range of 6 V to 10 V allows the TB6556FG to be compatible with a wide range of power sources, making it versatile for different applications, from consumer electronics to industrial automation. Overall, the TB6556FG is a highly capable motor controller that combines advanced features with ease of use, making it an excellent choice for driving brushless motors in various applications.TB6556FG 3-Phase Full-Wave Sine-Wave PWM Brushless Motor Controller, Sine-wave PWM control, Built-in triangular-wave generator (carrier cycle = fosc/252 (Hz), Built-in lead angle control function (0 to 58 in 32 steps External setting Automatic internal setting, Built-in dead time function (setting 2. 6 s or 3. 8 s, Overcurrent protection signa l input pin, Built-in Regulator (Vrefout = 5 V (typ. ), 30 mA (max), Operating supply voltage range: VCC = 6 V to 10 V By Toshiba Semiconductor 🔗 External reference
