n Available in 12-Pin 4mm × 3mm DFN,
10-Pin MSOP, and 16-Pin SO Packages The LT®4356-3 surge stopper protects loads from high
voltage transients. It regulates the output during an
overvoltage event, such as load dump in automobiles, by
controlling the gate of an external N-channel MOSFET. The
output is limited to a safe value thereby allowing the loads
to continue functioning. The LT4356-3 also monitors the
voltage drop between the VCC and SNS pins to protect …
