In robotics, motor driver ICs are frequently used to operate DC motors from microcontrollers.
They are commonly utilized in automation since they are an important component in controlling motion in autonomous robots. They’re also found in more everyday places like workplace appliances and automobile electronics.
The Europe motor driver IC market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2026, registering a CAGR of XX% from 2022 to 2027.
Toshiba Electronics Europe GmbH (“Toshiba”) has announced the release of a three-phase brushless DC (BLDC) motor control pre-driver IC for high-speed motors such as server fans, pumps, blowers, and suction motors for cordless and robotic vacuum cleaners.
The new Toshiba TC78B011FTG features a sine-wave drive system that reduces vibration and noise. Its sensorless design saves space and money by eliminating the need for a Hall sensor.
Without the use of an external microcontroller, the built-in closed loop speed control regulates and maintains the motor’s rotational speed throughout dynamic power supply fluctuations and load variations (MCU). The built-in non-volatile memory can be programmed to precisely set a speed profile (NVM).
Allegro MicroSystems Europe’s A3903 is a low-voltage bidirectional DC motor driver IC in a 2 mm square and 0.55 mm high ultra-compact packaging.
The new device has a typical input voltage range of 3 to 5.5 V and can deliver up to 500 mA of output current. To provide a constant voltage across the motor coil, the output uses a full-bridge circuit with source-side linear operation.
Motor voltage changes caused by current variations and battery voltage fluctuations are minimised with this regulated output.
