Toshiba releases new motor control driver IC
Summary
The SmartMCD TB9M003FG uses Toshibas advanced mixed-signal process technology, combining an Arm Cortex-M0 CPU with a vector engine co-processor and pre-drivers to control external B6 N-channel MOSFETs. This level of integration of the device, which is housed in an HTQFP48 thermal enhanced package measuring 9.0 x 9.0mm, allows for smaller, simpler and lower-cost 30 – 1000W BLDC motor systems. The device simply connects directly to the battery and local interconnect network (LIN) bus, which features a built-in wake-up for power-efficient operation and communication. The SmartMCD incorporates current limiter, overcurrent, VBAT overvoltage, and overtemperature protection circuitry, and fault detection for undervoltage, external power MOSFET open/short failure and overheating. The SmartMCD Motor Studio PC tool allows for easy parameter configuration, drive control, real-time logging and diagnostics via a high-speed UART.
