A current limit can be programmed using an external resistor connected from the IL pin to GND. This programmed current limit (±20% accurate) refers to the continuous current through the device and therefore, when operated at its maximum current rating (6 A), the programmed current limit needs to be set 20% higher. As shown in Figure 8-2, a current limit event of this nature is defined as a soft short. The resistor value RIL, can be calculated using Equation 7 for VIN ≤ 3 V, and Equation 8 for VIN > 3 V, where IL is the programmed current limit value in amperes. This programmable current limiting feature is different from the internal current limiting activated during fast trip mode as shown in Figure 8-3. A current limit event in this case is defined as a hard short and this current limit (typical of 22 A) cannot be programmed.
