STMicroelectronics EVLPWD-FAN-PUMP PWD5T60 Circular Reference Design

STMicroelectronics EVLPWD-FAN-PUMP PWD5T60 Circular Reference Design is a 3-phase inverter featuring the STM32G071RBT6 Arm® Cortex®-M0+ microcontroller and the PWD5T60 motor driver. The STMicroelectronics EVLPWD-FAN-PUMP PWD5T60 is designed for applications like fans and pumps, offering a configurable single or three-shunt sensing topology. The board supports field-oriented control (FOC) and 6-step control, enabling it to drive permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors. Additionally, a current comparator provides a cycle-by-cycle current limiter for current mode control.
