The TMPM370FY is ideal for motion control in home appliances and industrial applications where it reduces the need for additional components while providing significant benefits over software-based vector control running on a microcontroller.
Based on the ARM Cortex-M3 core running at 80MHz, the new device operates from a 5.0V supply and integrates Toshiba’s proprietary PMD3+ programmable motor driver technology, a vector engine (VE) 12-bit ADC functionality and a comprehensive set of peripherals and interfaces into a single 100-pin IC. The result is compact, highly efficient device that can simplify applications requiring precision control of sensored and sensorless three-phase brushless DC (BLDC) motors or three-phase induction motors. Offloading motor control to the PMD3+ means that the ARM core is free to manage other elements of the embedded design.
The two channel PMD3+ block and the single channel VE manage all of the functions needed to control a motor including three-phase PWM waveform generation at 16-bit resolution, speed control and position estimation. The 12-bit ADC provides high-speed, PWM-synchronised analogue-to-digital conversion, while an on-board comparator can be used for detecting emergency stop conditions. Other on-board features include a regulator, a single-channel encoder, power-on-reset/low-voltage detection, a watchdog timer and an 8-channel 16-bit timer.
