MAX5949B Datasheet -48v Hot-swap Controllers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-3494; Rev 1; 8/11 MAX5949A/MAX5949B -48V Hot-Swap Controllers with External RSENSE.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.

Key Features

  • o Allow Safe Board Insertion and Removal from a Live -48V Backplane o Pin and Function Compatible with LT4250L (MAX5949A) o Pin Compatible with LT1640L (MAX5949A) o Pin and Function Compatible with LT4250H (MAX5949B) o Pin Compatible with LT1640H (MAX5949B) o Circuit-Breaker Immunity to Input Voltage Steps and Current Spikes o Withstand -100V Input Transients with No External Components o Programmable Inrush and Short-Circuit Current Limits o Operate from -20V to -80V o Programmable Overvoltage.
