Inrush current is limited to a programmable value by controlling the gate voltage of an external N-channel pass transistor. The pass transistor is turned off if the input voltage is less than the programmable undervoltage threshold or greater than the overvoltage threshold. A programmable electronic circuit breaker protects the system against shorts. The PWRGD (LT1640L) or PWRGD (LT1640H) signal can be used to directly enable a power module. The LT1640L is designed for modules with a low enable input and the LT1640H for modules with a high enable input. The LT1640L/LT1640H is available in 8-pin PDIP and SO packages. s Central Office Switching s – 48V Distributed Power Systems s Negative Power Supply Control Hot Swap is a trademark of Linear Technology Corporation. , LTC and LT are registered trademarks of Linear Technology Corporation.
