Hi,
I'm using the DRV8106SQRHBR-Q1 in my design,
I am facing an issue when testing the output current sensing.
For my test I have a Resistive load (1A) and I drive it with 100% duty cycle PWM (the goal of the test is only to validate the current sens function)
My configuration of the CSA_CTRL register (Dh) is :0x82
CSA_SH_EN : 1 Enable current shunt amplifier sample and Hold
CSA_BLK_SEL : 0 (I let this at the default value)
CSA_BLK : 000 (the blanking time is disabled)
CSA_DIV : 0 (for my design I need to measure current in source and sink mode)
CSA_GAIN : 10 (40V/V)
The issue is I thinkg that the amplifier is not enabled. I have the same output voltage from the amplifier (0.6V) whatever is load (even in open load)
Am i having a wrong configuration ?
from where can come my error ?
Thanks in advance
