G5250e/f/g/h, G5250i/j/k/l and G5250m/n/p has open- drain oc output reports over-current or over-temperature event and has typical 9ms deglitch timeout period. pin configuration typical application circuit r ul recognized component r ul recognized component v out v in c out 22 f c in 1 f in en gnd out on off v out v in c out 22 f c in 1 f in en gnd out on off flag 100k oc G5250a/b/c/d G5250e/f/g/h,G5250i/j/k/l,G5250m/n/p out 5 4 1 in 2 3 gnd en oc en out sot-23-5/tsot-23-5 5 4 1 in 2 3 gnd out G5250a/b/c/d G5250e/f/g/h in en 5 4 1 oc 2 3 gnd out G5250m/n/p (en) (en) (en) sot-23-5/tsot-23-5 sot-23-5/tsot-23-5 in en 5 4 1 oc 2 3 gnd out G5250i/j/k/l (en) sot-23-5/tsot-23-5 v out v in c out 22 f c in 1 f in en gnd out on off v out v in c out 22 f c in 1 f in en gnd out on off flag 100k oc G5250a/b/c/d G5250e/f/g/h,G5250i/j/k/l,G5250m/n/p out 5 4 1 in 2 3 gnd en oc en out sot-23-5/tsot-23-5 5 4 1 in 2 3 gnd out G5250a/b/c/d G5250e/f/g/h in en 5 4 1 oc 2 3 gnd out G5250m/n/p (en) (en) (en) sot-23-5/tsot-23-5 sot-23-5/tsot-23-5 in en 5 4 1 oc 2 3 gnd out G5250i/j/k/l (en) sot-23-5/tsot-23-5
