Part Number: DRV8841 Other Parts Discussed in Thread: DRV8702-Q1 Hi , m a newbie to commerical electronics ...was a hobbyist...pls helpme out
What is the input voltage I have to provide the "xIN1" and other inputs pins of the IC, does it need to be 5v…
Part Number: DRV8841 Other Parts Discussed in Thread: DRV8412 , , SM72295 Hi,
I'm worrying which IC is better for Step Motor control, DRV8841 or DRV8412. In DRV8412 Datesheet, tDT(Dead time between HS and LS FETs) is written. On the other hand, tDT is…
Part Number: DRV8841 Other Parts Discussed in Thread: DRV8844 , , DRV8842 , DRV8828 , DRV8829 As the DRV8844 is currently not available, I'm searching for a "second source".
I need two half-bridges to drive solenoids. The DRV8841 could be an…
Part Number: DRV8841 Other Parts Discussed in Thread: TMS320F28055 , Tool/software: Code Composer Studio Hello, I found a recent forum thread with a similar topic but I want to be more precise, and possibly i would like to receive more precise response…
Part Number: DRV8841 Other Parts Discussed in Thread: DRV103
I am working on a project that requires driving 4x solenoids at 24V (1.58A each). I was originally interested in the DRV103 for the PWM operation that conserves power while the solenoid is…
Part Number: DRV8841 Customer use DRV8841, meet OCP issue, the design follow DRV8841EVM.
The max current through the motor is 1.3A, Risense is 0.36, Vref is 2.5V, so Ichop = 2.5/(5*0.36)=1.389A.
Sometimes the motor will be locked, but the current is below…
Part Number: DRV8841 Hi team,
The customer is using DRV8841.
In first mode it should pump around 200mA where as in another mode it should drive around 80mA current.
The attached is the customer's schematics based on DRV8841IC for drive circuit where SOV…
Part Number: DRV8841 Hello,
As per the datasheet the decay pin controls the decaying mode of the motor coil. However the decaying path can also be provided by making XIN1 "low" and XIN2 "high" for fast decaying ;and making both XIN1 and XIN2 "low" for…
Part Number: DRV8841 Hello,
I was testing the ic with Vm=24 volts by applying the load of 10.8 ohms and a load coil of 1.2ohms resisrance and 4.2 mH indutance with pwm applied at 50% duty cycle. While testing
I got only error ripples on dso. After checking…
Part Number: DRV8841 Other Parts Discussed in Thread: DRV8844 , DRV8840 Hi,
I have noticed that the DRV8841 outputs have a phase jitter in the range of about 400ns and I believe it might be causing micro-stepping problems. I'm driving a 3 phase stepping…
