n Available in (4mm Г— 3mm) 12-Pin DFN,
10-Pin MSOP or 16-Pin SO Packages The LTВ®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 …
