The demonstration Circuit 1850A-B showcases the LTC?4366 high voltage surge stopper in a 28V vehicular application. The DC1850A-B withstands inputs of up to 100VDC and input transients of up to 250V while maintaining the output at 43.1V. Reverse battery and errant inputs of up to -100VDC are blocked from reaching the output. It features auto-retry 9 seconds after tripping off in an over voltage fault condition. The 9 second delay can be interrupted by pulsing the SHUTDOWN input.
