Part Number: DRV8703D-Q1 Other Parts Discussed in Thread: DRV8703-Q1 I’m seeing conducted emissions when the DRV8703 is not held in sleep mode, with a fundamental around 130-140kHz and many higher-order harmonics. This happens whenever the H-Bridge…
Part Number: DRV8874 Hello, would it be possible to use the "VCP" pin of the D RV8874 to perform reverse supply protection, similar to drv8703? If possible, what would you consider?
I have find out this following EVM boards & read all the document files related to this boards so out of all boards I can see input voltage range or Operating Voltage Range of this boards but in that document files I'm not able to find that EVM…
Part Number: DRV8840 Hello, would it be possible to use the "VCP" pin of the DRV8840 to perform reverse supply protection, similar to drv8703? If possible, what would you consider?
This is expected behavior. The DRV8702-Q1, DRV8703-Q1, DRV8702D-Q1, and DRV8703D-Q1 monitor the charge pump as the device is waking and entering sleep.
nFAULT is asserted during this time.
Please refer to
The nFAULT assertion can be…
The DRV8701, DRV8702-Q1, DRV8702D-Q1, DRV8703-Q1, and DRV8703D-Q1 are our closest devices. Speed control and hall-sensor feedback may need to be controlled by external circuitry. We do not integrate those features in these devices.
Your conclusions from your scope shot and experiment of changing the resistors are reasonable to me. It looks like having additional impedance in the gate-drive path was causing the issue. Thanks for doing this experiment and sharing your data…
Part Number: DRV8703D-Q1EVM Other Parts Discussed in Thread: DRV8703-Q1 , DRV8703-Q1EVM Hai,
Thanks for responding to my previous forms.
we want to control DRV8703-Q1 driver IC in DRV8703D-Q1EVM ( Evaluation Module ) with external micro, so as per my raised…
Part Number: DRV8703D-Q1EVM
Please resolve the following issues as early as possible
1.While connecting DRV8703 q1 evm board ,'NO USB FET was FOUND ' like this error was coming..i tried a lot methods which are suggested in forum and also in google…
