Part Number: DRV8881 Other Parts Discussed in Thread: DRV8825 Hi team,
My customer is considering if DRV8825 can be used as DRV8881P P2P compatible assembly option.
Do you think it is possible?
My customer thinks the interface pins (#21-24) can…
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 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 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

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 Hi,
I am working on schematic layout of DRV8881 on Altium and I have two questions:
I was wondering what value of current sense resistor should I use and how can I find footprint for sense resistor at Altium? (Pin AISEN and…
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 …
Part Number: DRV8881 Hi Rick,
I'm working with Thomas Bewley on a project to model the motor dynamic for both braking and coasting during low PWM cycles. We're also investigating the effect of the PWM frequency and the coasting during low PWM cycle…
Part Number: DRV8881 I have a confusion about the DRV8881 "decay modes" (slow, fast, 30/70, and, on the DRV8881E, AutoTune). Do these modes
a) come into play only when current regulation is triggered (as discussed section 7.3.4 of the DRV8881 datasheet…
Part Number: DRV8881 Hello team,
The customer has a question about current sense useing Rsense. When the current reach to Itrip, DRV8881 start to behave in decay mode. How long does it take from reaching to Itrip until DRV8881 start decay mode. I belieave…
