TheSH\ISEpin allows foldbacklimiting of theload current, with circuit breaker action after a programmable delay time. The delay allows the part to power-up in current limit. The CRWBR output can be used to trigger an SCR for crowbar load protection after a programmable delay if the input supply exceeds a programmable voltage. The RESoutput can be used to generate a system reset with programmable delay when the supply voltage falls below a programmablevoltage. The ON pin can be used to cycle the board power. The LTC1642 is availablein the 16-pin SSCP package. LTC and LT are registered trademarks of Linear Technology Corporation. Hot Swap is a trademark of Linear Technology Corporation.
