Part Number: DRV8821 Other Parts Discussed in Thread: DRV8885 , DRV8880 , DRV8886 I have a DRV8821 driving a stepper motor at 1 amp peak. If I grab the motor and force it to turn when it is energized and stationary, the motor de-energizes. Probing the…
Part Number: DRV8821 Hello,
Attached is a picture with the design of the DRV8821. It is connected to a microcontroller. J4 and J7 connect to 2 bipolar stepper motors.
The signals provided by the microcontroller are as follows:
STEP=pulse
DIR=0…

iWe are developing a battery-powered device. We have to control 2 stepper motors, so we are using DRV8821. We need to de-energize both motor windings to save energy. To do that, I set high signals ABENBLn and CDENBLn to disable…
Part Number: DRV8821 HI
TPS54331DDAR, TPS2069CDBVR, TPS54531DDAR, DRV8821DCAR IC
It is difficult to obtain the above material, so we have to supply other IC.
Are there any material that are fully compatible with above material?
Part Number: DRV8821 Hello,
I am Ananth from Chennai.I have used the driver IC drv8821 with a stepper motor.I am operating the motor in the various PPS. I will explain the flow below
1.I have rotate the motor initially from 200- 1200 PPS in 100…

Hello sir:
About DRV8821 control, we meet a problem need help.
The below picture is catch from Scope and you can find the B Bridge is slow 1/4 wave of A Bridge.
From DRV8821 datasheet…
Hi Aju,
The DRV8821 stepping angles are fixed by the internal indexer. Any of the stepper motors that have an internal indexer have fixed stepping angles.
The minimum step angle of the DRV8821 is 11.25 degrees electrical angle. Please note many…
Part Number: DRV8821 using DRV8821 , It works fine with a step motor with 2.5 ohm resistance.
However with other set motor with a resistance of 100 ohm , The motor is making
noises and is not moving.
Any Idea ?.
