Description
General part information
MAX5948 Series
The MAX5948A/MAX5948B are hot-swap controllers that allow a circuit card to be safely hot plugged into a live backplane. The MAX5948A/MAX5948B operate from -20V to -80V and are well-suited for -48V power systems. The MAX5948A is pin- and function-compatible with both the LT1640AL and LT1640L. The MAX5948B is pin- and function-compatible with both the LT1640AH and LT1640H.The MAX5948A/MAX5948B provide a controlled turn-on to circuit cards preventing glitches on the power-supply rail and damage to board connectors and components. The MAX5948A/MAX5948B 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 MAX5948A and MAX5948B protect a system against overcurrent and short-circuit conditions by turning off the external MOSFET in the event of a fault condition.Both devices feature an open-drain power-good status output, active-low PWRGD for MAX5948A or PWRGD for MAX5948B, that can be used to enable downstream converters.The MAX5948A/MAX5948B 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 SwitchingNetwork Routers and SwitchesServer Line Cards
