Part Number:DRV8301
Hello,
In the datasheet of DRV8301 http://www.ti.com/lit/ds/symlink/drv8301.pdf , it is written under "Overcurrent Protection and Reporting (OCP)" section:
"There can be up to a 20% tolerance across channels for the VDS trip point"
The question is: as I want to limit my motor current to 2A and I want to limit it exactly to this value in order to use maximum torque possible, is the above method is reliable?
In other words, is the tolerance is because there are limited values for Vds threshold (see table in p23) ? or whatever the value I choose from the table is to have that tolerance?
If you have better way of limiting the current accurately using DRV8301 on-chip resources, please suggest it
Thanks
