Part Number: DRV8834 Hi team,
When driving stepping motor with DRV8834 in indexer mode, is it supported to control Ifs with xVREF? My customer wants to use it to actively control the trip current depending on motor's driving or stopping state. However…
Part Number: DRV8834 Hi team,
As per Table 6 in Section 9.2.2.1 of the datasheet, can the DRV8834 only drive a stepper motor at 6V? If a 10-V stepper motor is to be driven, can VM be applied at 10 V? Or what kind of circuit should be added?
Could you…
Part Number: DRV8834 Hi,
I have a project which is in production right now. Our company has not worked on the design but we are building production units for this project.
One of the recent issues which came up was a component getting knocked off while…

Hi Team,
Could you please let us know Min and Max value of AISENSE at TA=-40 ℃ to 85 ℃ ?
Because, we would like to know the error of ITRIP without error of xVREF and RISENSE.
Regards,

Part Number: DRV8834 Hi, I'm using DRV8834 to drive a small stepper motor to open/close an air vent. If a user manually opens the vent, we think the backdrive may be causing a small number of field failures as the energy from the manually rotated motor…
Part Number: DRV8834 Hi All,
Our smart glasses project needs to use a stepping motor to achieve diopter adjustment and interpupillary distance adjustment functions. The specific parameter requirements are as follows:
1) D iopter adjustment: 3.6V input,…
Part Number: DRV8834 Hi team,
Here's an issue from the customer may need your help:
When using the DRV8834 to control the stepper motor, the indexer mode of 8834 is required (16 microsteps are used simultaneously). In addition, the peak of the output…
