Part Number: DRV11873 Hi, TI expert
I posted the same question on E2E, but there was no response for over 7 days, so I am making a new inquiry to E2E. (Existing inquiry: e2e.ti.com/.../drv11873-request-for-review-of-drv11873-circuit- and-defect-improvement…
Part Number: DRV11873 Hi, TI expert
Our customer is using the DRV11873PWPR for the stirring motor used in the water purifier.
However, due to continuous defects, there are inquiries as to whether the surge resistance can be increased to check if there…
Part Number: DRV11873 Hi, TI expert
After the Motor Control Board (featuring DRV11873) produced by the customer is installed in the final equipment, the BLDC motor-equipped water purifier set, intermittent FG detection failure is occurring due to FG output…
Part Number: DRV11873 Hello,
I'm trying to use a 9v battery to power a hard drive disc motor with DRV11873 plus a 555 timer and LM391 rectifier.
-I'm finding more reliable startup with a 5400mwh rechargeable 9v battery than a non-rechargeable one…
Part Number: DRV11873 From the datasheet of DRV11873:
8.4 Device Functional Modes 8.4.1 Startup At startup, commutation logic starts to drive the motor with one phase high, one phase low, and the third shut off. If a zero-cross is detected on the shut off…
Part Number: DRV11873 hi,
DRV11873 drive motor does not rotate, please help analyze, thank you!
The test results are as follows:
a. Measure input voltage/signal is normal;
b. Measuring the motor drive board driver chip DRV11873, it was found that the…
Part Number: DRV11873 Hi team,
For the title says, I have a motor with a rated power of 20 W. How do I calculate the output power of the driver to ensure that it can drive the motor?
For example, how to calculate the output power of the driver at a set…
Hi Venkatadri S,
Thank you for the support.
The customer also performed several start-stop tests and grabbed the waveform of the instant current at startup. Occasionally, a waveform as shown in the figure below will appear with an instantaneous peak voltage…
