Ready-to-use board ideal for battery-powered 3-phase motor control applications up to 75 V
Supporting FOC and 6-step algorithms, both sensor-less and sensored, this flexible solution is based on the STDRIVE101 low-voltage, triple half-bridge gate driver. Built around a 128-Kbyte STM32G0 MCU and STL220N6F7 STripFET F7 Power MOSFETs, this compact board (50 mm ⌀) is ideal for applications requiring high output currents. Compatible with the STM32 motor control software development kit.
