TC78B011FTG is three-phase brushless DC (BLDC) motor control pre-driver IC incorporating a sine-wave drive method reducing vibration and noise. Its sensorless design saves the space and cost of a hall sensor. 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). Precise setting of a speed profile can be programmed into the built-in non-volatile memory (NVM).
Operating from a supply voltage ranging from 5.5 to 27V, the feature-rich device includes selectable closed loop or open loop speed control. Speed can either be controlled through a PWM signal, analog voltage or via the I²C interface. The I2C interface is also used to control various settings within the device. A standby function further improves overall system efficiency.
Applications
The device is suitable for motors that require high rotation speeds, such as those used for server fans, pumps, blowers and suction motors for cordless and robotic vacuum cleaners.

The TB67H451AFNG enhances product sourcing possibilities and features a convenient non-latching overcurrent detection. It can drive brushed DC motors and is capable of operating from a wide range of input voltages, from 4.5V to 44V. The maximum motor drive output current is 3A at 44V and several protection mechanisms are built-in to the device including undervoltage lock out (UVLO), auto-return thermal shut down and non-latching overcurrent protection (OCP). OCP is a safety funcion that prevents damage to the IC by turning off the output when the output current exceeds the pre-set threshold level. Toshiba’s TB67H450AFNG features a latching overcurrent detection, where output is turned off indefinitely until a power cycle or entering and leaving the standby mode. However, the TB67H451AFNG is non-latching and resumes function automatically after a programmable recovery time once the overcurrent condition is removed.
Applications
TB67H451AFNG (and its predecessor TB67H451FNG) supports numerous applications including battery powered devices and other devices with a 5V USB power supply and is also suitable for use with many 12-36V industrial devices, home appliances such as coffee machines and robotic vacuum cleaners, fiscal printers and electronic door locks that require a high-current drive of up to 3.5A.
