Hello,
I am currently testing the DRV3946 and have some questions regarding the CRC8 calculation. I am having difficulty calculating the CRC8 for CONFIG_A6, CONFIG_B4, and the CMD registers.
Could you please provide…
Part Number: DRV3946-Q1 Tool/software: I have a recommendation from our customer to use the DRV3946 for EV applications. Can someone share the Application Note of this chip. Any preliminary schematics is available?
please share the information as early…
Part Number: DRV3946-Q1 Tool/software: Hi expert
From the table below, we can see the UCLO current is derived from hold current. The hold current will be a range because of RIPROPIx and AIPROPI.
Which hold current should we calculate with, the max or the…

Part Number: DRV3946-Q1 Tool/software: Hello again,
I have been working with this device off and on for a while and finally got it MOSTLY working. I was informed by the test team recently that the device is not operating the spike and hold functionality…
Part Number: DRV3946-Q1 Tool/software: Hi Application team:
We want to get DRV3946-Q1 IBIS model for SPI simulation but we cannot see on the Ti.com.
could you provide the simulation model file for SI simulation ?
Thank you

Part Number: DRV3946-Q1 Tool/software: Is it possible to use the DRV3946-Q1 in a 24V system?
The input supply to the device could be provided from a 12V rail, but the OUT1, OUT2 input voltages could be as high as 40V (absolute max). Is that a problem…

I am planning to use the high side switch TPS1HTC30-Q1 with low side driver DRV3946-Q1 (the high side switch being shared between the two loads). …
Part Number: DRV3946-Q1 Tool/software: Hi,
How to calculate DRV3946-Q1 V IPROPI ? Is it (Iout(A) / A IPROPI ) x R IPROPI ?
Please help to check, thanks.
