When GCSA is set to 20 V/V When Tj temperature changes from 25°C to 175°C → By approximately what percentage does the gain value change? Additionally, when including the outputs up to the SOA/SOB/SOC pins, if there are any factors other than GCSA error that affect current sensing accuracy, I would appreciate it if you could also provide this information.DRV3256-Q1https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1651371/mct8329a-mct8329a-sporadic-register-value-freeze-when-reading-via-i2c/6369958Thu, 04 Jun 2026 00:06:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:5cb32b37-82cd-430b-b4b2-6785235c7c73DhineshHi Peter, It is recommended to implement this workaround for the MCT8329A to avoid this I2C issue. We have a newer variant - MCF8329HS (Hardware compatible to MCT8329A) that includes an integrated sensorless FOC algorithm. Could you please recommend customer to use the MCF8329HS for their application?

DRV output can be HiZ. Please refer table 7-9/10/11.. However, this HiZ meant both external HS and LS FET are OFF. Weak pull up path to PVDD exist.

Since DRV8718Q1 has common VDS_LVL setting for all 8CH, GL7 will trigger with lower current by additional shunt_R. I believe your VGL_LVL is typo, you meant VDS_LVL. If Door/lock/unlock and hood release motor will not turn no at the same time, following configuration will work? As drawback, HS and LS VDS over current level will have mismatch, due to Shunt R. regards Shinyahttps://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1652135/drv8312-bootstrap-capacitor-selectionWed, 03 Jun 2026 22:25:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:914d7271-1176-47e4-aeec-8c6ab3fac806Julie SilversPart Number: DRV8312 Other Parts Discussed in Thread: DRV8313 Hello, I am working on a design which involves replacing a DRV8313 with a DRV8312. I am caught on this note in the DRV8312 datasheet: "For applications with lower than 10 kHz switching frequency and not to trigger BST_UVP protection, a larger bootstrap capacitor can be used (for example, 1-uF capacitor for 800-Hz operation)". Our application is very low frequency compared to this part's specification. We are operating at 5Hz nominally. Is this of concern for this part? There is no minimum frequency listed in the specification. Will I need to go higher than 1uF for the bootstrap capacitor with a frequency this low? And what are the potential implications to increasing this? I have already implemented the 5 ohm resistors between GVDD and GVDD_X, and am planning on 10x the bootstrap capacitance on each GVDD_X pin. Going much higher than 10uF will be a big constraint on board space.drv8312DRV8313Aerospace & Defensehttps://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1644512/launchxl-f28379d-line-245-error-148-declaration-is-incompatible-with-void-pm_tformat_setupcommandreadoutorreset/6369828Wed, 03 Jun 2026 21:53:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:58afda0c-7043-4cc5-a365-02051ea610b9Stevan DuraskovicHi, I will need more time to look into this and get back to you.https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1644301/launchxl-f28069m-quadrature-current-and-phase-current-bldc/6369597Wed, 03 Jun 2026 18:37:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:e5d3ecb4-9e54-4d23-a5bf-a1fd03a447b2Jiaxin TengHi Luca, Phase current is AC signal, so the amplitude is equivalent to the maximum value.

Due to the high peak current requirements of the motor, I am planning a "Split-Supply Configuration" as follows: 1. VM Pin: Connected to a 9.7V boosted rail via the TPS61088 boost converter to ensure sufficient gate drive voltage (VGS) and avoid UVLO during battery voltage drops. 2. Inverter Power (MOSFET Drains): Connected directly to the 2S Li-Po battery (nominal 7.4V) to supply high current. 3. VDRAIN Pin (Pin 37): Connected directly to the 7.4V battery rail (same as the MOSFET drains) for correct VDS overcurrent sensing. Questions: 1. Is it completely acceptable to operate the DRV8323 with different voltages on the VM pin (9.7V) and VDRAIN pin (7.4V)? 2. Will this separate power configuration cause any issues with the internal logic, charge pump, or VDS overcurrent protection (OCP) mechanism? Thank you for your support!TPS61088DRV8323https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1652100/mct8376z-q1-operate-without-hall-sensorsWed, 03 Jun 2026 17:34:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:5d0e6522-0e0a-47ac-ac3a-7fd2a1b0f6acAlan BeverlyPart Number: MCT8376Z-Q1 Longterm I plan on using Hall sensors, but for mechanical testing with a motor without Hall sensors can I configure the hardware version of the part for operation using the evaluation board?MCT8376Z-Q1https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1651456/drv8300-need-support-for-gate-driver-drv8300n-for-driving-dc-and-bldc-motor/6369345Wed, 03 Jun 2026 16:02:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:4786620e-ede9-437d-bf74-ce508e49b4d4Joseph FerriHello, 1. Yes, you can drive a DC motor, but you will need to PWM 2. No, you will need to turn low side on in order to charge BST capacitor to turn on high side MOSFET. 3. Yes, you will need to turn on low side MOSFET to charge, it will not operate at 100% duty cycle.

You can find graphs characterizing this in the Typical Characteristics section of the device data sheet.https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1651573/drv8245-q1-multi-devices-spi-connection/6369213Wed, 03 Jun 2026 14:56:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:9a1fa2f9-6f0d-4e88-9cca-6640cf9e8563Joshua Horlander CruzHi Hanbing, I think option one is better by helping reduce the number of resistors, but why does this solution need to use a separate SDO pin for the non DRV8245 device? I think the SDO output pin could be shared still even with this configuration? For the configuration, I would recommend considering using a daisy chain connection for connecting all the DRV8245-Q1 devices together to help reduce the number of GPIO pins needed since with daisy chain only one nSCS pin is needed. More information about daisy chain can be found in the DRV8245-Q1 datasheet.

The reason given was to contact your local TI sales office to have a valid TI NDA in place in order to allow for document access approval. All of our automotive safety devices are covered under NDA. Once your company has an NDA in place then you can request access to the documentation.

In my first post I tried to include some screen shots that would show versions, but this is what I see for the SDK That is 5.04.00.00. CCS is 20.5.1.12_1.11.1. If that does not answer your question, let me know how to get the right information for you. We bought this kit about 6 months ago, and I finally got time to start with it early in May (a month ago). So we did not have old versions lying around. This was all done in the last month. Are there specific files that you could tell me to look for to check for correct versions? Sorry that I can't be more help, but CCS and this processor are all new to me. It's very likely something that I have done wrong, but I don't know what. I did find a load map, but in a quick look I don't see anything in it showing any version numbers. The good new is that, after my changes to the source, it is compiling and executing. I am getting data back from a TS5700 encoder. So I can make progress. But I would like to get this straightened out eventually because something is not right. Let me know what info I can get for you or things I should try or redo. Thanks for all your help.
