9.2.2.1 Programming the Current-Limit Threshold R(ILIM) Selection

The R(ILIM) resistor at the ILIM pin sets the overload current limit. The overload current limit can be set using Equation 10.

Equation 10. R I L I M = 18 I O L = 18 k Ω

where

  • ILIM = 1A

Select the closest standard 1% resistor value: R(ILIM) = 18kΩ
