Part Number: DRV8334 Tool/software: Hello
We use DRV8334 in PMSM motor drive and we measured strange noise signal on outputs of current sense amplifiers.
We measure current on two phases with 0.5 mOhm shunt and max current is 35 A RMS.

Part Number: DRV8334 Other Parts Discussed in Thread: DRV8323 Hi team,
Could you please erabolate whether VM can be up to 36V or up to 60V?
I'm suggesting to E-bike customer with Li-ion 7S (29.4V DC max) and Li-ion 10S (42V DC max), who has been using…
Part Number: DRV8334 Tool/software: Hello,
Is there any limitation to the size of the cap used for Cbst on the DRV8334? Any concerns with a cap up to 2.2uF (or larger) in value?
I see a recommended value of 1uF to 1.5uF in the datasheet.
Thank you…
Part Number: DRV8334 Tool/software: I see in the datasheet in MON_CTRL3 a bit called "VGS_LVL". Is this threshold solely used for the VGS protection, or does it play a role in other aspects of the gate driver (eg, smart gate drive)?
Part Number: DRV8334 Tool/software: Hi GD team,
Our design is utilizing various DRV8334 protection features, and in particular we are getting close in normal operation to the Vsense protections, we wanted to know the general distribution of the values…
Part Number: DRV8334 Tool/software: Dear support team,
I use the DRV8334 and the PVDD is connected to a regulated 12V supply. Currently I'm using the charge pump mode for GVDD and the system works fine. However I'm wondering if the LDO mode is sufficient…
Part Number: DRV8334 Other Parts Discussed in Thread: DRV8323 Tool/software: Hi, I'm considering a BLDC motor driver choice for a project and these two drivers seem roughly equivalent. The only guidance I've found is the related question linked from this…
Part Number: DRV8334 Tool/software: Hello,
Could you please confirm whether the phase comparator is a latching fault when set to fault mode in firmware?
Thank you, Keith
