LM63: Register

Part Number: LM63

HI Expert

Thank you for solving the hardware design problem,
I have a question about register settings. Before using the fan control IC in the data sheet, four registers must be set. Please give four register recommendations based on fan specifications.
  • FAN operationg frequency: 25KHz

 

Q1: Is the value of register 4A set to 0x20?

Q2:The product will use three target duty cycles (60%, 70%, 80%). But I don’t know the setting rules in register 4B? Please give formula.

Q3: Is the value of register 4D set to 0x7?

Q4: The product will use three target duty cycles (60%, 70%, 80%). But I don’t know the setting rules in register 4C? Please give formula.
