EVLPWD-FAN-PUMP

EVLPWD-FAN-PUMP is a 3-phase complete inverter based on the STM32G071RBT6 Cortex®-M0+ microcontroller and PWD5T60 3-phase motor driver evaluation board. The evaluation board has been designed, in terms of characteristics and form factor, to address some of the main product applications of the PWD5T60, such as fans and pumps. The board has a configurable single or three-shunt sensing topology, and both the FOC and 6-step control can be implemented. This allows PMSMs and BLDC motors to be driven. A current comparator allows the cycle-by-cycle current limiter feature to implement a current mode control. The presence of on-board bus voltage sensing can be exploited for overvoltage or undervoltage protection. The driver, in addition, has an undervoltage lockout mechanism to protect against VCC supply voltage drop. The driver built-in overcurrent circuitry allows almost immediate hardware protection, without the intervention of the microcontroller.
