Description
General part information
MAX5920 Series
The MAX5920A/MAX5920B are hot-swap controllers that allow a circuit card to be safely hot plugged into a live backplane. The MAX5920A/MAX5920B 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 MAX5920A/MAX5920B provide a controlled turn-on to circuit cards preventing glitches on the power-supply rail and damage to board connectors and components. The MAX5920A/MAX5920B 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 MAX5920A and MAX5920B protect a system against overcurrent and short-circuit conditions by turning off the external MOSFET in the event of a fault condition. The MAX5920A/MAX5920B also provide protection against input voltage steps. During an input voltage step, the MAX5920A/MAX5920B limit the current drawn by the load to a safe level without turning off power to the load.Both devices feature an open-drain power-good status output (active-low PWRGD for the MAX5920A or PWRGD for the MAX5920B) that can be used to enable downstream converters. A built-in thermal-shutdown feature is also included to protect the external MOSFET in case of overheating.The MAX5920A/MAX5920B are available in an 8-pin SO package. Both devices are specified for the extended -40°C to +85°C temperature range.ApplicationsBase-Station Line CardsCentral-Office Line CardsNetwork Routers and SwitchesServer Line CardsTelecom Line Cards
