Description

The EVLPWD-FAN-PUMP board is a 3-phase complete inverter based on the STM32G071RBT6 Cortex®-M0+ microcontroller and PWD5T60 3-phase motor driver.


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 field-oriented control (FOC) and 6-step control can be implemented. This allows permanent magnet synchronous motors (PMSMs) and brushless DC (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.

The possibility to use a temperature sensor completes the set of protection features.

The demonstration board is compatible with a wide range of input voltages and includes a power supply stage with the VIPER011LS in buck configuration to generate the +12 V and +3.3 V supply voltages required by the application. The input stage of the board is equipped with a complete AC mains line filter.

Programming and debugging of firmware can be performed with standard STM32 tools through an external STLINK debugger (such as STLINK/V3).
