Tool/software:
There are the following questions about the UVP peripheral resistor design of DRV632
The cut-off voltage of UVP is 1.25V. In the design of external detection resistors, there are two formulas proposed, one is 6uA and the other is 5uA. These two current values represent the current flowing from where to where? Are they flowing towards R2 and R3 respectively? In that case, wouldn't the current flowing through R1 be 11uA?
If it is based on the current size of problem 1, then in the For example, when R1=3K, R2=1K, and Vuvp=3.8V, the current of the resistor is much greater than 11mA
If my system voltage is 24V or 3.3V, how many R1, R2, R3 should I design? Can you guide me on the design process? Thank you!
