Overview
19-3494; Rev 1; 8/11 MAX5949A/MAX5949B -48V Hot-Swap Controllers with External RSENSE General Description The MAX5949A/MAX5949B are hot-swap controllers that allow a circuit card to be safely hot plugged into a live backplane.
The MAX5949A/MAX5949B operate from -20V to -80V and are well-suited for -48V power systems.
These devices are pin and function compatible with the LT4250 and pin compatible with the LT1640.
The MAX5949A/MAX5949B provide a controlled turn-on to circuit cards preventing glitches on the power-supply rail and damage to board connectors and components.
The MAX5949A/MAX5949B provide undervoltage, overvoltage, and overcurrent protection.
These devices ensure the input voltage is stable and within tolerance before applying power to the load.
Both the MAX5949A and MAX5949B protect a system against overcurrent and short-circuit conditions by turning off the external MOSFET in the event of a fault condition.
The MAX5949A/MAX5949B also provide protection against input vol...
