An internal high side switch driver controls the gate of an external N-channel MOSFET for supply voltages from 2.9V to 26.5V. A dedicated 12V version (LTC4218-12) contains preset 12V specific thresholds, while the standard LTC4218 allows adjustable thresholds. The LTC4218 provides an accurate (5%) current limit with current foldback limiting. The current limit threshold can be adjusted ...
