Part Number: DRV8886AT Other Parts Discussed in Thread: MSP430F2617 Hi team,
Do we have a list of commands for a customer to use on their own Labview app to control the DRV8886AT Evaluation Module (the list that we use for our GUI)? The GUI works as…
Hi user6151353,
The DRV8886AT can drive a 1.5A rated motor, assuming proper thermals on the PCB.
What is the desired RMS current setting? If it is 1.4A or less (RREF resistor is 20kOhm or greater), the device can drive current this with proper therma…
Hi, James.
I received the DRV8886AT EVM board yesterday. the test result is not satisfied.
Below is the comparison test,use DRV8886ATEVM and use H company drives (the main core part is DSP + MOSFET), blue for DRV8886ATEVM test current waveform, white…
Hi David,
May I suggest you evaluate the performance with our DRV8886ATEVM in parallel. There is a header on the EVM that allows you to disconnect the mcu and control the device with your system.
Marcos,
I am not sure how quickly it responds, but I know that it is fairly responsive. We do that exact implementation on the DRV8886EVM and DRV8886ATEVM.
There are two variants of the DRV8886. The DRV8886AT variant uses our smart tuning decay modes…
Hi Aditi,
May I suggest you obtain one or two DRV8886ATEVM for evaluation. One EVM can be used without modification to see how the device operates. The second EVM can be modified to accept external mcu control.
The mcu typically needs some type of PWM…
Hi Matthew,
TVS diodes are typically not required next to the driver for operation. The DRV8886ATEVM does not have them.
TVS or other protection circuits may be required for voltage spikes (ESD for example) at the motor terminals.
Hi Santosh,
The code provided with the DRV8886ATEVM is intended to highlight operation of the device when interfaced with a GUI.
There are many examples of sample code online. One site to visit is energia.nu/.../
Hi Dean,
It is recommended to check for voltage spikes when powering down. Also you should check to ensure the current is being regulated properly in 1/8 modes.
If space is a constraint, there are other devices that are smaller with similar capabilities…
Hi John,
Since you are considering switching to the DRV8880, please take a look at the DRV8886AT also. This device has AutoTune plus integrated current sensing. The recommended maximum voltage range is 37V.
The DRV8886ATEVM hardware files are also available…
