Linear Technology’s LTC4366 is an over-voltage protection controller for electronic systems. Operating from 9 V to greater than 500 V, the device utilises an adjustable floating topology to enable very high-voltage operation independent of the voltage rating of its 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 device was said to be the first product of its kind to protect, for example, a 12 V circuit from a 500 V transient without the need for additional protection components.
The chip monitors the voltage at its output and reacts quickly to input supply over-voltage by controlling the gate of an N-channel MOSFET. It regulates the output to a user-defined voltage during an over-voltage transient, allowing the load to remain operational while the over-voltage is dropped across a MOSFET. An adjustable fault timer ensures safe shutdown if the fault persists.
The LTC4366 is ideal for harsh industrial, automotive and avionic applications where systems must continue operating reliably through severe over-voltage events. High-voltage applications include protecting from motor transients, coupled over-voltage, incorrect input supplies or power supply failures.
