TheLTC®7860highefficiency surge stopperprotects loads from high voltage transients. 

High efficiency permits higher currents and smaller solution sizes. 

During an input overvoltage event, such as a load dump in vehicles, the LTC7860IMSE#PBF controls the gate of an external MOSFET to act as a switching DC/DC regulator (PROTECTIVE PWM mode). 

This operation regulates the output voltage to a safe level, allowing the loads to operate through the input over-voltage event.

During normal operation (SWITCHON mode), the LTC7860IMSE#PBF turns on the external MOSFET continuously, passing the input voltage through to the output. 

An internal comparator limits the voltage across the current sense resistor and regulates the maximum output current to protect against overcurrent faults. 

An adjustable timer limits the time that the LTC7860IMSE#PBF can spend in overvoltage or overcurrent regulation. 

When the timer expires, the external MOSFET is turned off until the LTC7860IMSE#PBF restarts after a cool down period. 

By strictly limiting the time in PROTECTIVE PWM Mode when the power loss is high, the components and thermal design can be optimized for normal operation and safely operate through high voltage input surges and/or overcurrent faults. 

An additional PMOS can be added for reverse battery protection.
