www.onsemi.com Adjusting Current Limit As shown in Figure 28, a combined 46 k /C0087 internal resistance (3R + R) is connected to the inverting lead on the PWM comparator. An external resistance of Rx on the ILIMIT pin forms a parallel resistance with the 46 k/C0087 when the internal diodes are biased by the main current source of 50 /C0109A. For example, FSL336LR has a typical SENSEFET peak current limit of 1.8 A. Current limit can be adjusted to 1.2 A by inserting RX between the ILIMIT in and the ground. The value of the R X can be estimated by the following equation: 1.8 A : 1.2 A /C0043(46 k/C0087/C0041Rx):R x (eq. 1) Figure 28.
