MAX5921 Datasheet -48v Hot-swap Controllers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-2946; Rev 1; 2/06 MAX5921/MAX5939 -48V Hot-Swap Controllers with External RSENSE and High Gate Pulldown Current.

General Description

The MAX5921/MAX5939 hot-swap controllers allow a circuit card to be safely hot plugged into a live backplane.

The MAX5921/MAX5939 operate from -20V to -80V and are well suited for -48V power systems.

These devices are pin patible with both the LT1640 and LT4250 and provide improved

Key Features

  • over these devices. The MAX5921/MAX5939 provide a controlled turn-on to circuit cards preventing damage to board connectors, board components, and preventing glitches on the power-supply rail. The MAX5921/MAX5939 provide undervoltage, overvoltage, and overcurrent protection. These devices ensure that the input voltage is stable and within tolerance before applying power to the load. Both the MAX5921 and MAX5939 protect a system against overcurrent and short-circuit conditions by turning off the.
