Part Number: DRV8881
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: DRV8833 Other Parts Discussed in Thread: DRV8881 Hi everybody,
In a previous question i asked some questions about the possible values for Rsense on this IC.
I assumed that once the current through the motor exceeded the set limit (Ichop…
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…
Part Number: DRV8881 Other Parts Discussed in Thread: TIDA-00641
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…

Hi all Would you mind if we ask DRV8881E? We have some questions which are relation to follows E2E forum. http://e2e.ti.com/support/motor-drivers/f/38/p/772361/2856520#2856520 Our customer would like to DRV8881E for BDC at only A side…
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 BISEN…
