Toshiba Launches SmartMCD Series Gate Driver ICs with Embedded Microcontroller
Toshiba Electronic Devices & Storage Corporation ("Toshiba") has started volume shipments
of the SmartMCD Series of gate driver[ ICs with embedded microcontroller (MCU).
The first product, "TB9M003FG," is suitable for sensorless control of three-phase
brushless DC motors used in automotive applications, including water and oil
pumps, fans and blowers.
TB9M003FG combines
a microcontroller (Arm Cortex-M0), flash memory,
power control functions and communications interface functions into a gate
driver that controls and drives N-ch power MOSFETs for three-phase brushless DC
motor drives. This integration will reduce system sizes and component counts
while realizing advanced and complex motor control for a wide variety of
automotive motor applications. The new product also incorporates Toshiba's
proprietary vector engine, hardware for sensorless sinewave control, reducing
the load on the microcontroller, and the size of the software.
The expanding
market for electric vehicles (xEV) requires electrification, component
integration, downsized electronic control unit (ECUs), and quieter motors. In
response, the new product contributes to downsizing of ECUs by integrating a
microcontroller into the gate driver, and to quieter motors by using vector
control.
