Part Number: DRV8452 Tool/software: Hello,
Is it possible to connect all the ground pins of the DRV8452PWPR to a negative voltage rail to create an offset ground plane? If so, is there a limit to the offset (as long as the Vm-to-ground voltage stays…
Part Number: DRV8452 Tool/software: In the datasheet of the DRV8452 the recommended maximum step frequency is 100kHz, while in the timing requirements it is 500kHz. It does mention the motor load and that this can impact the maximum frequency, but not…
Part Number: DRV8452 Other Parts Discussed in Thread: DRV8462 , DRV8462EVM Tool/software: Hi team,
Do not seem to have an EVM for DRV8452, just for DRV8462.
What is the difference between the DRV8452 and DRV8462?
Would it be ok to evaluate the DRV8462EVM…
Part Number: DRV8452 Tool/software: Hi ,
for DRV8452, there are two package available, do they both have Kv=0.66?
DDW Package: 5 A full-scale, 3.5A RMS
PWP Package: 4 A full-scale, 2.8A RMS
IFS *Kv= Vref, KV=0.66,
for PWP package: Max Vref = 4A*0.66…
Part Number: DRV8452 Tool/software: Hi,
for using DRV8452,with H/W interface, we are only using Step/ direction and there is no Pin for Vcc on page 4 and foot print. however, on page 17 and 18 we see the recommended 1uF cap to GND the VCC pin.
Part Number: DRV8452 Other Parts Discussed in Thread: DRV8462EVM , DRV8462 Tool/software: Hi,
Could you provide a tuning guide for DRV8452 or a development guide using the GUI (DRV84XX-DRV89X2-DRV82X2-EVM-SOFTWARE)? I would like to clarify what steps…
Part Number: DRV8452 Tool/software: Hi,
The design condition was 160,000pps, but due to the constraints of the evaluation board, it was confirmed at 65,536pps or less. The pulses/second is assumed to be 160,000pps, but the maximum ƒSTEP is stated as…
Hi Takemura-san,
All SPI register writes will take effect immediately after the nSCS pin goes logic HIGH after the SPI frame. So TRQ_DAC update will go in effect immediately after nSCS = HIGH.
You mentioned "In order to achieve energy savings and provide…
Hi Murugavel, I have done some work around DRV8452, I have tested it again but nothing changed.. Since I dont have the EVM board, I would like to do some test before I buy the board, because than I dont see any choice... Could you please set the driver…
