RS31316AR

Hot Swap Controllers Overview

The RS31316AR is a hot swap controller and electronic fuse manufactured by Reed Semiconductor Corp. It operates within an input voltage range of 4.5V to 16V and supports a maximum current limit of 20A. The device features an integrated pass MOSFET with an on-resistance of 2.7mΩ. Current limiting is adjustable from 2A to 20A, and it includes an adjustable over-current blanking timer for load protection. The component is housed in a 26-pin WFLGA package with exposed pads.

Hot Swap Controllers Feature Summary

• Integrates a low-resistance pass MOSFET for efficient power handling
• Provides adjustable current limiting capabilities across a wide range
• Includes programmable over-current blanking timer for fault management

Hot Swap Controllers Applications

• Hot swap system protection
• Industrial equipment power distribution
• PCI/PCIe application interfaces

Hot Swap Controllers Procurement Notes

Verify the specific ordering suffix AR against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad specifications. Ensure that the 26-WFLGA package dimensions match the target PCB footprint requirements. Cross-reference the lead time information provided by authorized distributors with the manufacturer's standard delivery schedule to align with production timelines. Confirm active status directly through official channels before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring robust hot swap protection with adjustable current thresholds. The wide input voltage range suits various industrial power rails. Consider the exposed pad thermal design for adequate heat dissipation given the high current capacity. Evaluate the need for adjustable blanking timers to accommodate specific inrush current profiles during system startup or module insertion events.

Hot Swap Controllers Part Context

This part belongs to Reed Semiconductor's family of electronic fuses and hot swap controllers. These devices are designed to protect sensitive electronics from overcurrent and short-circuit conditions. The RS31316AR specifically targets applications needing precise current management and safe insertion/removal capabilities in high-reliability environments.

Hot Swap Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative components such as the LTC4216 or ADM1281 only if their datasheets explicitly state functional equivalence and pin-to-pin compatibility for the specific application requirements.
