Dear Team,
Absolute maximum rating of nSLEEP pin of DRV8424 is VVM (max).
Recommended operating condition of VI (Logic level input voltage) is 5.5V (max)
Electrical characteristics of LOGIC-LEVEL (nSLEEP), VIN is 1.5V (min) to 5.5V (max).
When the input voltage to the nSLEEP is higher than 5.5V, but lower than VM=24V, what operation mode does the DRV8424 become?
My customer is evaluating the DRV8424RGER with VM=24V.
Under M0=M1=0 for Full step setting, the DRV8424RGER operates Full step normally with nSLEEP > 5.5V.
However under M0=M1=1 for 1/8 step setting, the DRV8424RGER does not operate 1/8 setp with nSLEEP > 6.9V, the DRV8424RGER operates Full step. If nSLEEP < 6.5V, the DRV8424RGER operates 1/8 step normally. Why does the DRV8424RGER not opearate 1/8 step under nSLEEP > 6.9V and M0=M1=1? The DRV8424RGER operates what mode?
Thank you.
Best Regards,
Koshi Ninomiya
Hello team,
My customer is considering DRV8231 for driving solenoid.
My customer is wondering which decay mode should they use, slow decay (Brake) or fast decay (coast)?
I understand the benefit of fast decay becuase it will decay faster, but is there any benefits of chosing slow decay instead?
If there is no benefit in choosing slow decay, I will tell my customer to use fast decay.
Best Regards,

hi Expert,
i want ask two question about DRV8889-Q1
first, customer find the register 0X0A is 0X03 not the default, why happen this condition
Second , how to do the Stall Detection, csutomer want to test the Stall detection, but they don't know how to set up hardware and software。
Dear TI team:
I have written to RAM register to change configure data, but it doesn't takes effect at the first motor start-up. While at the twice motor start-up, it works.
Why this occurs? And how i can make the register works at the first motor start-up after register writes?
The flow is a example to describe my operation steps:
1) I write MOTOR_STARTUP1(84H) register by I2C communication, to configure ALIGN_TIME=1(=50 ms);
2) I control the motor rotated and then stop.
3) I write MOTOR_STARTUP1(84H) register, to configure ALIGN_TIME=2(=100 ms);
4) I control the motor rotate, and measured the real align-time is 50 ms, not 100 ms. But I read back the MOTOR_STARTUP1(84H) register, which the ALIGN_TIME=2(=100 ms);
5) I stopped the motor , and rotate it again. Now I measured the align-time is 100 ms.
Hello Team,
I am trying to spin a motor using DRV10983 EVM, behavior is as shown. Seems EVM tries to "Align" but never switches to "Go"
Attached is a video, as well as motor configuration file used in the GUI.
Thanks,
Mohamed

Hi TI
When I use DRV8714 in my design，I developed Offline Short Circuit and Open Load Detection (OOL and OSC) function now.
I find a strange phenomenon, which is when I enable EN_DRV and disable EN_OLSC again, Vds status do not be cleared, which is still staty last status.
My step is
1. Seting IC_CTRL1 as 0x56(disable EN_DRV and enable EN_OLSC),
2. Setting OLSC_CTRL1 as 0x99
3. Read VDS_STAT1 is 0x66.
4. Seting IC_CTRL1 as 0x96(enable EN_DRV and disable EN_OLSC)
5. Read VDS_STAT1 is 0x66.(I think it should be 0x00)
Hi Team,
Due to footprint is so complicated, TPSM861257EVM have Gerber file?
Have you guys been able to roll out the new version of the EVM which does not have the fault that did not allow the EVM to be operated above 48V.??
I am setting the align current limit as per my motor's datasheet and equations given in MCT8329A
SLLSFQ3 – JANUARY 2023 document at Page-82. However, my two motors have been burnt during startup?
Please resolve
Hi, I am trying to use the MCT8316Z with a supply above 24v. It works fine until about 27v, then the buck out drops from 5v to aprox 2v and I get a bulk faults condition. The bulk is supplying 3 hall effects sensors in the motor. The datasheet says the MCT8316 has a 40v absolute maximum capability. I was hoping to run it at 35v.
HI,
Using the DRV8210 but like to save GPIOpins , is it possible to both set supply VCC, MODE and EN pins at the same time from same GPIO pin and just before doing that also select PH high or low for forward or reverse of the motor.
regards
Mats
I'm new to how ripple counting works. I'm trying to replace an encoder in my system. I was wondering if I can rotate the motor shaft, then get a read on the angle im rotating using ripple counting. Is that possible?
Hi,
I have question on this two setup to control a peltier module.
We would like to maintain the temperature of a DUT 40 degree celsius. So for example if the DUT goes above 50 degrees we would like to cool it down to 40 degrees back, if it go to 30 degrees we would like to heat it back to 40 degrees. May I know which are solution are more suitable for my applications? It seem like both of the IC are using PWM input. Can help if there any others reading material on peltier module would be helpful.
thank you and best regards
Does the placement of an external sense resistor affect the PWM current regulation?
Also, what is the resistance value of the internal current detection?
Team,
My customer is thinking to use DRV8256 between 0.1A ~ 0.5A. I have some questions here;
1. Does DRV8256 have capability to drive BDC motor at such small current?
2. If yes, what is Itrip accuracy between 0.1A ~ 0.5A? There are Itrip accuracy information in the electrical characteristics table but no information less than 0.5A.
Thanks,
Nobuhiko Wasa
This is a request for investigation into the acceptance defect of DRV3205. The event is as follows: Gate output NG The IC alone shorts between GHS(#13) and SHS(#14)
Please investigate the above. Deadline: May 21th
Also, I believe we will need to request an investigation into the IC alone regarding the estimated cause, so we appreciate your cooperation at that time.

Hi TI
When DRV8714 output normally, and output short to gnd / short to battery, how to diagnostic this fault?(not offline diagnostic )
Hi,
Kind regards,
