RS31313AR

Hot Swap Controllers Overview

The RS31313AR is a single-channel hot-swap controller manufactured by Reed Semiconductor Corp. Designed for PCI and PCI-X applications, it integrates an internal power switch capable of handling up to 5A output current. The device operates within a supply voltage range of 2.97V to 16.5V and supports a maximum operating junction temperature of 125°C. It utilizes a compact 10-VFDFN (3x3) surface-mount package with an exposed pad for thermal management.
