LT1161 - Quad Protected High-Side MOSFET Driver

Also included in each switch channel is a drain sense comparator that is used to sense switch current. When preset current level is exceeded, the switch is turned off. The switch remains off for a period of time set by an external timing capacitor and then automatically attempts to restart. If the fault is still present, this cycle repeats until the fault is removed, thus protecting the MOSFET.

The LT1161 has been specifically designed for harsh operating environments such as industrial, avionics, and automotive applications where poor supply regulation and/or transients may be present. The device will not sustain damage from supply voltages of -15V to 60V.
