Q
nn 8-Lead TSOT and 3mm × 2mm DFN Packages The LTC®4366 surge stopper protects loads from high
voltage transients. By controlling the gate of an external
N-channel MOSFET, the LTC4366 regulates the output
during an overvoltage transient. The load may remain
operational while the overvoltage is dropped across the
MOSFET. Placing a resistor in the return line isolates the
LTC4366 and allows it to float up with the supply; therefore,
the upper limit on the output voltage depends only on the
availability of high valued resistors and MOSFET ratings. nn APPLICATIONS
