MAX5933AESA+

Hot Swap Controllers Overview

The MAX5933AESA+ is a positive high-voltage hot-swap controller designed for safe insertion and removal of circuit boards under power. It supports input voltages from 33 V to 80 V with a single channel. The device features an adjustable current limit of 1.88 A, enabling controlled inrush current during board insertion. Operating within a temperature range of -40°C to +85°C, it utilizes an SOIC-8 surface-mount package. The quiescent supply current is 1.4 mA, and the maximum power dissipation is rated at 470 mW.

Hot Swap Controllers Feature Summary

• Provides controlled hot-swap operation for high-voltage backplanes
• Integrates adjustable current limiting to manage inrush currents
• Includes power-fail detection for system protection

Hot Swap Controllers Applications

• High-voltage backplane card insertion systems
• Telecommunications equipment power modules
• Industrial control board hot-plug interfaces

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited availability. Confirm RoHS compliance status via official documentation. Check current distribution status as Mouser indicates restricted supply in certain regions. Ensure ordering suffix matches required packaging specifications.

Hot Swap Controllers Selection Notes

Select this controller for applications requiring robust protection during live board insertion. Verify that the 33 V minimum operating voltage aligns with the system bus requirements. Consider the 80 V maximum rating when designing for higher voltage environments. Evaluate thermal management needs given the 470 mW power dissipation limit in the SOIC-8 package.

Hot Swap Controllers Part Context

Part of the MAX5933 series of hot-swap controllers from Maxim Integrated. Designed specifically for positive high-voltage applications where board replacement must occur without powering down the system. Complements other PMIC solutions by handling transient power events safely.
