LTC: overvoltage protection controller for electronic systems

Linear Technology introduces the LTC4366, an overvoltage protection controller for electronic systems. Operating from 9V to greater than 500V, the LTC4366 floating surge stopper utilizes an adjustable floating topology to enable very high voltage operation independent of the voltage rating of the LTC4366’s internal circuitry.  Two internal shunt regulators coupled with the external voltage-dropping resistors generate the LTC4366’s internal supply rails. The maximum operating voltage is set by the breakdown of the external resistors and MOSFETS. The LTC4366 is the first product of its kind to protect, for example, a 12V circuit from a 500V transient without the need for additional protection components. The LTC4366 monitors the voltage at its output and reacts quickly to input supply overvoltage by controlling the gate of an N-channel MOSFET.  The LTC4366 regulates the output to a user-defined voltage during an overvoltage transient allowing the load to remain operational while the overvoltage is dropped across a MOSFET. An adjustable fault timer ensures safe shutdown if the fault persists.

The LTC4366 is packaged in a tiny 8-lead TSOT-23 and 3 x 2mm DFN packages. During operation, the entire circuit consumes only a few milliamperes, and the device may be shut down to less than 20µA. The LTC4366 is available in two options; the LTC4366-1 latches off after a fault, while the LTC4366-2 will retry after a 9-second cool down period. Devices are specified over the full commercial, industrial and automotive temperature ranges.
