9.2.2 Detailed Design Procedure
To keep the 0.25-A nominal current in the 0 to 4-V current-sense range, calculate the R(CS) resistor using Equation 9. To achieve better current-sense accuracy, a 1% tolerance or better resistor is preferred.
Equation 9. 
To set the adjustable current limit value at 0.5 A, calculate R(CL) using Equation 10.
Equation 10. 
TI recommends R(ser) = 10 kΩ for 5-V MCU, and R(pu) = 10 kΩ as the pullup resistor.
