We have a similar motor driver device that features sensorless FOC integration (MCF8329HS), which is also hardware compatible with the MCT8329A.

In our case MODE pin is set to Ground. If I float it then polarity of waveform will same (non-inverted). 2. I will increase boot cap to 1uF. My question is as below: For DC Motor: 1. Will this IC works to drive DC motor without PWM? 2. Can I make high side MOSFET full ON (100% Duty Cycle) and Low side MOSFET Low to drive DC motor? 3. Will this IC need low side MOSFET turn ON first to charge and then it will turn ON high side MOSFET?https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1651367/drv8718-q1-drv8718-vgs_lvl-with-shunt-r-on-the-low-side/6368395Wed, 03 Jun 2026 03:56:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:1429abce-83d0-4bc7-8f4a-5e5d67d8329eShinya MoritaHi, Thank you for your questions.

Please follow the below instruction to recover the device from this condition. 1.In the system, read the contents of register address 0x6DE periodically. Wait time between reads – must be atleast 200ms. 2.If the read value (16bits) at 0x6DE ( MEM_SEC = 0x0, MEM_PAGE = 0x0, MEM_ADDR = 0x6DE ) exceeds 200 (decimal), the device status will not be updated and CLR_FAULT commands will not take effect. 3.Once scenario mentioned in 2 is detected, give the following I2C frames to recover the device: – Step 3a : Read the contents of the following address: MEM_SEC = 0x8, MEM_PAGE = 0xD, MEM_ADDR = 0x0 and store it (say the stored value is named VAR1). – Step 3b : (OR) the stored value (VAR1) with 0x0001 and store in another variable say VAR2 – Step 3c : write the value in VAR2 into the same address – Step 3d : Wait for at least 100ms – Step 3e : Write the original stored value VAR1 back into the same address Thanks, Dhineshhttps://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1644418/drv8718-q1-question-about-low-iq-powered-off-braking-pob-brake/6368136Tue, 02 Jun 2026 22:52:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:3fe1ccd6-15f3-404f-af3d-437ab53073c1Shinya MoritaHi Chase, Thank you for your questions. I am not familiar with your customer's situation. Is motor burned out by high current? Please refer bellow. POB is trying to change current path to contain VM increasing. Therefore, current level itself could be similar by POB active. This is my understanding. Does your customer observe higher current in POB? If yes, I am curious customer's measurement result. What type of solution did your customer use in previous platform? How they avoid this situation before? regards Shinya Moritahttps://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1651156/drv8889-q1-drv8889-q1-trq_count-stuck-at-70-in-cw-direction-only-ccw-normal-all-settings-match-evm-reproduced-without-load/6368092Tue, 02 Jun 2026 22:11:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:80b10d73-4593-4335-bdb9-c5257900ad76Murugavel4637Hi Jongyeon, [quote userid="630110" url="~/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1651156/drv8889-q1-drv8889-q1-trq_count-stuck-at-70-in-cw-direction-only-ccw-normal-all-settings-match-evm-reproduced-without-load/6366547"]But isn't it possible to adjust the 200 on the development board so that the appropriate value comes out from my PCBA? I don't know the meaning of that figure clearly. If you say it's an appropriate figure, does it mean that my actuator is currently generating the appropriate torque to turn the instrument? The motor rotates even if it comes out to 70 and 200.[/quote] What I meant was values in the range of 200 looks abnormal due to not proper calculation. So although the real values were much lower abnormal incorrect values were reported. The stall detection function in the DRV8889-Q1 is "report only" and does not affect motor operation. The motor should run normally regardless of the TRQ_COUNT reported.

If so, should we restrict the DAC more? For example, 43.75 > 37%, or should I increase it more?? 43.75 > 50%[/quote] The values of 200+ are not true values and because of this it cannot be assume more reserve torque is available. Thanks for sharing the tabulated values. The values starting from 11.7 V looks to be in-line with what I would expect for such a stepper motor. The high counts at < 11.6 V are not correctly computed, could be because of not having proper tON and tOFF defined waveform at this speed. The CCW column is showing a lower count possibly due to higher friction or other mechanical loading while running in this direction. If we look at the current waveform I expect it be distorted below 12 V at this speed. If you could share the coil A or B current waveform it may give us clarity why is happening. Thank you.

The max output voltage on this pin is tested with a max of 5mA. It is not recommended to drive an LED from the nFAULT pin.

However, the fact that the problem persists with a resistive load and across all SR settings suggests the issue is not purely load-induced. A general guideline for bulk capacitance is 1–4 µF per watt of motor power. At 12V × 6A = 72W, you need 72–288 µF minimum of bulk capacitance on the VM pins. I see 100uF is being used, which should be ok, but have you seen any transients on VM during the output transient? If possible, could scope captures of the output voltages, VM supply, and current be taken during this event?

Switching Frequency Limitation The EVM documentation states a maximum operating frequency of 200 kHz. Given that one of the key advantages of GaN FETs is their ability to switch at significantly higher frequencies — up to 1 MHz and beyond — I would like to understand the reasoning behind this limitation. Is it driven by the PCB layout, passive components, thermal constraints, or another factor? Furthermore, is it feasible to push the switching frequency beyond 200 kHz during testing and evaluation? If so, are there any specific precautions or component changes you would recommend? LMG2650 IC Availability I also noticed that the LMG2650 ICs have recently been set to "Active" status. Could you please provide an estimated availability date or an expected timeline for when the devices will be available for ordering? Pulsonix PCB Design Data Finally, do you have PCB design files for the EVM board available in Pulsonix format? This would be very helpful for integration and layout reference purposes. Thank you very much for your support. I look forward to your response.

We have prepared one PCB using DRV8300N(DRV8300NRGER) gate driver to drive PMDC and BLDC motor. We have started implementation in firmware to drive DC motor but we are facing one issue. Issue: High side MOSFET is not turning ON. It gives steady 12V on output of gate driver. If we provide PWM with duty cycle of 50% with frequency of 10KHz then also it remains high at gate driver output. Observation: when we provide PWM (same frequency and duty cycle as mentioned above) pulses for low side MOSFET, then only it gives PWM output on gate of high side MOSFET. As per observation looks like issue with bootstrap. But looking at the values and part number, all are ok. Please provide your valuable feedback. I have attached schematic screenshots for reference for more clarity.Industrial AutomationDRV8300https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1651412/drv8311-drv8311-questions-regarding-minimal-pin-counts-and-pwm-allignementTue, 02 Jun 2026 09:26:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:5f12fc6c-c4f9-4a95-8b5a-b6cef1f982d2Thore MehrPart Number: DRV8311 I have an application where we have four cameras and to deal with rain it was chosen to use spinning lenses. One of the motor drivers in consideration is the DRV8311. In our scenario the rotation speed has to be just above a threshold and a synchronization between motors or individual speed controll is not necessary. I have a few questions regarding with how little pins we can get away with as the used MCU is already quite loaded: 1) Is the current feedback necessary in all of the variants? 2) If I use 3x PWM to drive motors, what alignment should the three pwm have? Can I just connect all four drivers in parallel to the three PWM channels? 3) If I don't care about synchronization can I just let PWM sync float? If I understand it right the minimal configuration using DRV8311P would just use the four tSPI pins (and maybe nFault if I don't want to poll it)like in figure 8-6 (or 8-34), and DRV8311S/H would just use 3xPWM like in figure 8-5?DRV8311https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1651377/drv8874-drv8874Tue, 02 Jun 2026 08:13:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:9bed589a-bae6-49ea-a35d-2cafbb2b1a9eWouter KragtPart Number: DRV8874 Hello team, What is the maximum allowable current that can be driven through the nFAULT (open drain) input?
