DRV8870EVM Datasheet PDF - TI

●The DRV8870EVM is a DRV8870 H-bridge PWM motor driver evaluation module. The DRV8870EVM is a complete solution for evaluating the DRV8870 brushed motor driver. It includes a voltage regulator to create 5V and a TLC555 timer configured to supply a PWM input to the DRV8870. The EVM also includes a potentiometer to adjust the speed of the motor by varying the duty cycle of the PWM and a second potentiometer to set the chopping current value. Jumpers are provided to configure each input to a logic low, logic high, PWM, or to allow user control of the inputs. Test points are provided for ease of monitoring the input and output signals. The DRV8870EVM only requires connections to the motor and power supply to operate.

● 6.5V to 45V operating supply voltage range

● On board 5V regulator

● Adjustable PWM duty cycle

● Adjustable current regulation
