Part Number: DRV8705S-Q1EVM Hi team,
Could you tell me how to change CSA configuration as unidirectional sense from bidirectional one?
Is it possible to do that by GUI?
Regards, Ochi
Part Number: DRV8705S-Q1EVM Hi Team,
How shall i need to calculate the SO Current. Can you please brief how should i bring current from ADC count ... (no idea how to bring assume any gain and please give some explanation)
Part Number: DRV8705S-Q1EVM HI Team,
if i made chip as DRVOFF when i again make ON shall i need update the registers as per requirement .
In Sleep case not needed is this correct?? (Registers are as my init already done)
Part Number: DRV8705S-Q1EVM Hi Ti Team,
If Motor Predriver output connected to BDC Motor still i can do Offline Short Circuit and Open Load Detection (OOL and OSC) Related Diagnostics Since my motor is connected??
Thanks in Advance.
Regards, …
Hi,
Thank you for your questions.
I found one critical issue on your schematic. Please remove your 100Kohm resister from Gate to GND. R33/R43/R58/R68. R32,R42,R50,R67.
Please refer datasheet. DRV is not designed to have resister between gate to…
Part Number: DRV8705-Q1 Other Parts Discussed in Thread: DRV8705S-Q1EVM
Tool/software:
I am testing a design that has two grounds. SL1 and SL2 pins go to the output GND, while all the other GND pins go to logic GND. I have found that if the output…
Hi Chase,
Thank you for your question.
Yes, it is normal.
GH=low and SHx = HiZ (HS FET and LS FET are OFF).
Please refer this FAQ. SH should have weak pull up. Your customer may have some weak load on SH pin then SH pin is not purely 0V. …
Part Number: DRV8705-Q1 Other Parts Discussed in Thread: CSD18512Q5B , DRV8705S-Q1EVM , Hello,
We are using the DRV8705SQRHBRQ1 motor driver in our application. Initially, we employed H-Bridge PWM Control, and the overcurrent fault was triggered correctly…
Hi Jie,
JIE LIU said: On the first question, Who powers the SHx and what is the flow of charge pump between SHx and GHx once powered on?
The charge pump allows the high-side gate drivers to properly bias the external N-channel MOSFET with respect…
