DRV11873评估模块（EVM）是评价DRV1187312-V，三相无传感器BLDC电机驱动器的完整解决方案。它包括被配置为提供一个PWM到DRV11873，一个电位器，通过改变PWM的占空比来调节电机的速度的TLC555定时器。在FG针跳线中，允许使用一个外部上拉电阻；在RD针跳线下，表示电动机已进入锁定保护状态。The DRV11873EVM is a complete solution for evaluating the DRV11873 12-V, three-phase, sensorless BLDC motor driver. It includes a TLC555 timer configured to supply a PWM to the DRV11873, a potentiometer to adjust the speed of the motor by varying the duty cycle of the PWM, a jumper on the FG pin to allow the use of an external pull-up resistor, and a jumper on the RD pin to indicate that the motor has entered a lock protection state. The DRV11873EVM also has a jumper on the FR pin to select forward or reverse and a jumper on the FS pin to vary for high- or low-speed motor applications. Power can be provided externally, up to 16 V, through the power header. The PWM, RD, FG, and GND signals are all brought out to surface mounted test points.The DRV11873EVM is configured so that connections to only the motor and power supply are required.
