Product details

The MAX5905ESA is a dual hot-swap controller. It integrates two independent channels in a single package, each controlling an external N-channel MOSFET to ramp the supply voltage smoothly. Typical applications include telecom line cards, server blades, RAID systems, and any redundant-power architecture where a board must be swapped without powering down the backplane.

There is no last-time-buy window or end-of-life notice in effect.

RoHS non-compliant — plan for leaded assembly or seek an alternate

This part is RoHS non-compliant, built with leaded solder terminations. Designs requiring full RoHS conformance will need a Pb-free alternate.

This is typical for low-volume prototyping or manual assembly lines. For automated pick-and-place, you will need to transfer to tape-and-reel or confirm your feeder setup accepts tubes.

Frequently asked questions

What are the typical applications for MAX5905ESA?

Typical applications include telecom line cards, server blades, RAID systems, and any redundant-power architecture where boards are hot-swapped into a live backplane.

How does MAX5905ESA compare to MAX5904?

The MAX5905ESA and MAX5904 are both dual hot-swap controllers from Maxim, but the MAX5905ESA is designed for negative-voltage systems (typically -48V telecom rails), while the MAX5904 targets positive-voltage rails. Verify your supply polarity before selecting between them — they are not pin-compatible substitutes.

What package does MAX5905ESA come in?

The MAX5905ESA is supplied in Bulk form — typically tubes or trays. The exact case style is an 8-pin SOIC (narrow body), which is the standard footprint for this type of controller.

Is MAX5905ESA RoHS compliant?

No, the MAX5905ESA is RoHS non-compliant. It uses leaded solder terminations and is not suitable for lead-free assembly processes.
