Part Number: DRV8881 Hi Team, we would like to seek on how to calculate for the output voltage on purely resistive load.
The supply voltage to the DRV8881P device is 14.7 to 15V. The torque is set to 99%. The AVREF and BVREF pins are shorted to V3P3.…
Part Number: DRV8881 Hi,
Could you please let me know the resistors value for the figure 28 and 29 waveforms? It is 0ohm right?
Can xISENs connect to GND if my customer don't need current regulation?
Thanks
Muk
Part Number: DRV8881 Hi,
My customer is evaluating DRV8881 and has a question.
Charge pump stops and VCP voltage goes low when sleep mode.
nFault is asserted when restarting from sleep mode because VCP is lower than V CPUV as the attached file .

Hi all Would you mind if we ask DRV8881? Could you let us know XVREF's Absolute maximum rating? The datasheet shows follows; Does it mean V3P3(with 3.3-V LDO turns on)+0.5V? Or, does it mean -0.3V to 3.8V? As the background of this…
Part Number: DRV8881 Other Parts Discussed in Thread: DRV8701 , DRV8702-Q1 , DRV8703-Q1 , DRV8704 Hi,
I am current using a Dual Half bridge driver IC with external mosfets from another manufacturer. I would like to know if I can use DRV8881 using external…
Part Number: DRV8881 Other Parts Discussed in Thread: OPA564 , , DRV8889-Q1 Hi there,
we are designing a simple 2-phase step motor driver. Motor spec is below.
We are considering design TWO demo boards using different Driving solution: PWM voltage drive…

Hi all,
I am thinking of a design using drv8881P to drive two BDC or one stepper motor (with microstepping function) with one BOM, instead of two BOM, i.e. drv8881P for BDC and drv8881E for…
Part Number: DRV8881 Hi all,
Could you please give me some comments or tips about the microstepping methods, DAC on Vref or PWM as TIDA-00641 ?
In my case, the IC would be using is the drv8881P which has the Vref range from 0.3V ~ 3V, I believe the range…
Part Number: DRV8881 Hi, What is the peak current of DRV8881? Or can you provide SOA data for internal FET?
Our customer are looking for a device that will not break when the output is short-circuited, and will have a protection operation. This device has…
Part Number: DRV8881 Hi all
Would you mind if we ask DRV8881P?
Customer uses Brushed DC motors with Para (parallel) feature. I think that the output voltage slowly becomes 0V when braking the motor with slow Decay. However, it will be -2.4V (according to…
