Part Number: DRV8833EVM Other Parts Discussed in Thread: TIDM-TM4C123IOTSTEPPERMOTOR , DRV8833 Tool/software: TI-RTOS I have a BoXZY 3d printer/cbc mill and laser engraver, that still runs off of an Arduino Mega. I want to upgrade the whole control board…
Hi Annie,
Thanks for your question.
When switching between forward and reverse the motor coil current will need more than a few ns to decay before switching directions. The limitation between switching directions would be the dead time (tdead = 450 ns…
Hi Charles,
Charles Moher said: Can someone comment on the motor to DRV8833 connections.
The four output connections refer to the H-Bridge A (AOUT1: Black, AOUT2: Red) and H-Bridge B (BOUT1: Blue , BOUT2: Green ). The order is followed from the above legend…
Sanghoon,
Have you considered looking at a motor drive chip to interface to the stepper motor. I have had projects that used the DRV8833 to interface to 5V stepper motors in the past. The stepper motor takes 5V but the driver chip allows input with 3…
Other Parts Discussed in Thread: DRV8833EVM , DRV8833 I am using the DRV8833EVM to drive two small DC motors from a LaunchPad. I provide a digital (HIGH or LOW) to xIN1 and a PWM value to xIN2 but the output to the motors seems to be responding incorrectly…
Other Parts Discussed in Thread: DRV8833 , DRV8833EVM Hi,
I'm using DRV8833 to create simple waveform. As you can see in following capture (upper one is output and bottom one is input), it is quite unstable. I want to see one straight line but it keeps…
Other Parts Discussed in Thread: DRV8833 , DRV8833EVM Dear All,
I have been having some trouble with the DRV8833. Everything seemed to be going well on the first revision of our board, where we used a MSP430 to send PWM signals to the motor driver chip…
