Part Number: DRV8824-Q1 Tool/software: Hi Sir,
In the motor stopped, how to eliminate the abnormal waveform at output pins for the below figure? Could you please advise some comment? Thanks!
Ch1: AOUT1; Ch2: AOUT2; Ch3: BOUT1; Ch4: BOUT2
Part Number: DRV8824 Hello Team,
The driver is operated in ½ step mode with slow decay.
Question: What is the state of the driver after power on?
Background: If the stepper motor is in the ½ step and is then switched off, it could make a ½ step…
Part Number: DRV8824 We are using DRV8824 to drive the stepper motor, and the rotation direction of the motor is not consistent with the direction set by DIR. Have you encountered similar cases of this problem?
Please refer to the measured waveforms below…
Part Number: DRV8824-Q1 Other Parts Discussed in Thread: DRV8824 Hi expert,
Customers use DRV8824 to drive stepper motors, occasionally motor rotation direction and DIR set direction are inconsistent.
below is test scope:
The first 12 segments were reversed…
Part Number: DRV8824 Other Parts Discussed in Thread: DRV8434 , , STRIKE Hello MD team,
I have a customer in retail automation that faced failure with DRV8824 in the past. Could you tell me the difference design concept or market failure situation between…
Part Number: DRV8824-Q1 Other Parts Discussed in Thread: DRV8824 The motor driver chip DRV8824 is set to 1/2 phase, and the software input STEP is fixed to 12PPS. However, the number of steps is inconsistent at the output of DRV 8824 (The actual number…
The motor appears to be a 3 amp max NEMA 23 motor - 57HBP56AL4 (2A 1.2NM) ( link2 )
user5883945 said: Do you think customer need use more load ability like DRV8452,
That motor is large, but I think a DRV8825 should be able to drive it. DRV8824 is probably…
Part Number: DRV8824 Other Parts Discussed in Thread: DRV8424 , DRV8711 What's DRV8824 internally limited spec.？
The datasheet shows 1.6-A Maximum Drive Current at 24 V and TA = 25°C.
If we use the VM is 12V, d oes it mean we can d rive it rea…
Part Number: DRV8824-Q1 Hi,
One of our requirement has a test to check Over Current Protection(OCP) and Thermal Shutdown(TSD). How to simulate this to get nFAULT pin Low. Kindly help us to resolve this.

Part Number: DRV8824 Hi team,
Customer captured a strange waveform as below. CH1 is fault, CH2 is A phase current and CH3 is B phase current. While the A phase current exceed the OCP threshold(1.8A min), the fault pin is pulled low. The strange point is…
