MAX5939 - -48V Hot-Swap Controllers

Download the MAX5939 datasheet PDF. This datasheet also covers the MAX5921 variant, as both devices belong to the same -48v hot-swap controllers family and are provided as variant models within a single manufacturer datasheet.

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.

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.
