Hello friends!
I have a question about the calculation about the Over Current Protection and Over current Shunt level.
Based on the datasheet of DRV8301,
Vo = Vref/2 - G(SNx - SPx).
If I put the all of the SN1, SP1, SN2, SP2 as Z(high-impedance, then what is the fomular of the Over current threshold level?
Is this relative with Overcurrent Trip configuration?
This is parameters of my application.
--------------------------------------------
SP1 : Z
SN1 : Z
SP2 : Z
SN2 : Z
Vref : 3V
G(Gain of amplifier 20V/V)
OC_ADJ_SET : 24(1.043V)
MOSFET Rds(on) : 9.8m ohm
-----------------------------------------------------
Could you give me the detail explanation include theory?
Thank you!!
