However, since the DRV2700’s boost voltage is limited to 105V, I proposed using a flyback configuration to achieve 150V operation. https://www.ti.com/lit/ug/slou407a/slou407a.pdf I have presented the example circuit found in section 8.1 Schematic of the aforementioned application note. And, customer intends to drive a 1µF capacitive load with a 100Hz sine wave, resulting in a load current of 30mA. Is it possible to achieve this type of operation using the DRV2700?

I would like to understand the internal activity and current consumption mechanism during the inactive state. Thank you.DRV81080-Q1https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1693302/drv8245-q1-drv8245-short-to-power-vbatt-13-5v-test-result-questionWed, 28 Oct 2026 08:19:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:154e27e4-08aa-4f1b-bdf6-13d9cc853e45kwon guyoonPart Number: DRV8245-Q1 power supply1,2=13.5V, PH/EN mode *OUT1 short to power(while OUT2 is OPEN) When the OUT1 node was connected to 13.5V and operated in the "forward" direction (at 4000 Hz with a 10% duty cycle), an OLA2 fault—indicating an open-load condition detected in the ACTIVE state on OUT2—appeared in the STATUS1 register.

During this condition, nFAULT and nDRVOFF are tied low. Could you please confirm whether this operating condition is acceptable for the device? Additionally, we would like to verify that there are no internal sneak/leakage paths from VDRAIN to GVDD when GVDD is turned off and VDRAIN remains powered. Specifically, we want to ensure that GVDD or any internal circuitry is not unintentionally back-powered through VDRAIN under this condition. Please let us know if there are any limitations, precautions, or recommended operating conditions for this use case.DRV8161https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1690283/mcf8315d-bldc-motor-fails-to-achieve-rated-rpm-at-specified-dc-bus-volatge/6523332Wed, 28 Oct 2026 06:40:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:48b8eec9-3fe3-447a-9eb0-77ba81209981Venkatadri Shantaram84961Hi Sandeep - Ji, I missed to respond to this thread, I will revisit the conversation and reply .

For discrete MOSFETs, datasheets often provide Ciss, Coss, and Crss versus VDS curves. Could you provide the equivalent capacitance vs. VDS characteristics for the internal MOSFETs of DRV81080-Q1, especially Coss (OUT-to-VM capacitance) as a function of VDS? This information is required to evaluate the charge/discharge behavior when the drain-source voltage changes.

Tuning software manual / menus: TI's MotorStudio getting-started guide covers GUI installation, prerequisites, and required motor inputs (rated voltage, current, speed, shunt resistance) used by SmartTune, plus the Optimization Wizard that exposes settings by motor operating stage (e.g., startup). However, this guide is explicitly introductory and does not include detailed per-parameter tuning explanations. 1 1 2. Configuration and tuning procedure: The MCF8316DEVM user guide documents EVM setup (4.5–35 V supply, phase/motor connections, BRAKE/DIR/DRVOFF configuration) and MotorStudio operation. 2 2 For parameter identification, MPET measures phase resistance, inductance, BEMF constant, and speed-loop Kp/Ki and writes them to shadow registers, though TI recommends SmartTune for this. 1 A separate application note covers the open-loop-to-closed-loop handoff procedure and related EEPROM settings. 3 For custom boards (not the EVM), SmartTune can be used by connecting an MCF83xx evaluation board's I2C interface to your board with a shared ground. 4 3. South Korea FAE/on-site support: Please share me email id, production details through message to me I will contact my team and get back to you. Follow up: Would you like me to compile the specific MotorStudio menu-by-menu breakdown (Guided Tuning vs. SmartTune vs. manual register view) from the available guides?

Alternatively, for a gimbal topology, we could use an external driver such as the DRV8311, paired with a controller to execute the motor control algorithm. The key specification for this application is extremely quiet operation (low acoustic noise), please check with customer and finalize the approach. Thanks and best regards, Venkatadri Shttps://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1692934/mcf8329a-position-mode/6523235Wed, 28 Oct 2026 04:52:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:0bef72b0-5804-4861-abe2-fa10717f8befDhineshHI Harshitha, Reducing speed overshoot can be achieved either by decreasing the proportional gain of the speed loop or by lowering the closed‑loop acceleration rate (CL_ACC) . Verify whether the AVS feature is enabled in the system configuration. When AVS is active, the motor coast during deceleration to prevent an increase in the DC‑bus voltage. To eliminate uncontrolled coasting during motor deceleration, disable the AVS feature and reduce the deceleration rate (CL_DEC). Adjust the integral gain of the speed loop to obtain a stable speed response in steady‑state operation and suppress low‑frequency oscillations, Thanks, Dhineshhttps://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1691803/am2432-new-patch-version-6-5-103-of-pru-am2432-cannot-connect-with-inovance-h5u-plc-through-ethercat/6523113Wed, 28 Oct 2026 01:35:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:457ed415-6244-4ad8-9ee4-8701afa886bfcurrinwangHi Aaron, Due to a change in the account organization I belong to, i am unable to download this file.

Or could we refer to external resistor typical value only? For example, is it OK to use 8.2k with 10% resistor? This violates RLVL2OF6 max spec.

There is still one problem with the project libraries. CMP-0122035-1 is missing from the project library. It is for the MCF8329A1REER component. It is the variant/alternate to the MCT8329A1REER component. Can you see if it is in the Altium vault - TI library and export/copy it for me to use? The original TI project will not successfully compare the schematic to the PCB without it.https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1692109/tms320f2806-request-proposal-for-traction-controller-solution/6522884Tue, 27 Oct 2026 20:35:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:5df8e23b-e479-4907-a7f4-ebe06df16e91Masoud FarhadiHi Sagar, To give you the most cost-effective and modern architecture, we recommend F28E12. The newer portfolios offer vastly superior processing performance, lower unit costs, better safety compliance features, and significantly modernized software tools. you can sample LAUNCHXL-F28E12X with booster pack ENM for DRV8323RH or DRV8329 to run the SW. The SW is available at C2000 motor control SDK.
