MAX4273EEE+

Hot Swap Controllers Overview

The MAX4273EEE+ is a single-channel hot-swap controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7V to 13.2V and supports an operating temperature range from -40°C to +85°C. The device is housed in a 16-pin QSOP package with surface mount installation. Key electrical characteristics include a supply current of 600 µA. It integrates programmable features such as auto-retry, circuit breaker functionality, current limiting, fault timeout, and latch-up fault protection.

Hot Swap Controllers Feature Summary

• Integrates comprehensive hot-swap protection including current limiting and fault timeout mechanisms
• Supports automatic retry and latch-up fault protection for system reliability
• Operates with low supply current to minimize power consumption during standby

Hot Swap Controllers Applications

• General purpose hot-swap circuit protection
• System board insertion and removal management
• Power distribution unit input protection

Hot Swap Controllers Procurement Notes

Verify the specific suffix EEE against the official datasheet to confirm the 16-QSOP package and commercial temperature grade. Ensure compatibility with the target supply voltage range of 2.7V to 13.2V. Confirm that the integrated current limit and fault timeout settings meet the design requirements without external components. Check for RoHS compliance status if required by the manufacturing process.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution is required for protecting loads during live insertion. The fixed internal architecture simplifies design compared to discrete solutions. Consider the 16-QSOP footprint constraints during PCB layout. Evaluate if the general-purpose nature meets specific application needs or if adjustable parameters are necessary, which may require different part numbers within the MAX4271-73 family.

Hot Swap Controllers Part Context

This device belongs to the MAX4271-73 series of hot-swap controllers. These parts are designed to manage the inrush current and overvoltage conditions associated with inserting cards into powered backplanes. The series offers various configurations for channel count and package types, providing flexibility for different power management architectures in industrial and telecommunications equipment.

Hot Swap Controllers Replacement Considerations

The MAX4273ESE+T is a pin-compatible alternative available in a 16-SOIC package. Verify that the SOIC footprint matches the existing PCB design if substitution is considered. Both devices share similar functional specifications within the MAX4273 family.
