Efficient motor vector control from an 5x5mm MCU
Delivered in a VQFN32 package, the 5x5mm vector control microcontroller incorporates Toshiba’s Vector Engine Plus (VE+) coprocessor and a pre-driver to enable brushless DC motor control. It can directly drive MOSFETs for complementary three-phase PWM output with a minimum unit of 25ns. Equipped with an ARM Cortex-M3 core capable of running at speeds of up to 40MHz, a 12-bit AD converter and an on-board vector control platform, the TMPM37AFSQG enables highly efficient, low vibration and low noise motor control, greatly improving motor performance. Also integrated into the device are an op-amp essential for current detection using a single shunt resistor and a comparator for over-current detection.
