MAX5931HEEP+

Hot Swap Controllers Overview

The MAX5931HEEP+ is a three-channel hot-swap controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1V to 13.2V and draws a supply current of 2.5 mA. The device features an automatic retry function, circuit breaker capability, current limiting, fault timeout protection, and under-voltage lockout (UVLO). It utilizes the VariableSpeed/BiLevel technology series and lacks internal switches. The component is designed for surface mount installation in a 20-QSOP package with dimensions of 0.154 inches (3.90mm) width. It supports an operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Hot Swap Controllers Feature Summary

• Integrates three independent channels for general-purpose hot-swap control applications
• Provides comprehensive protection including programmable fault timeout and under-voltage lockout
• Supports automatic retry mechanisms and precise current limiting functions
• Utilizes VariableSpeed/BiLevel technology for controlled power-up sequencing

Hot Swap Controllers Applications

• General-purpose hot-swap controller implementations
• Multi-rail power distribution systems requiring sequential or controlled insertion
• Industrial equipment requiring robust overcurrent and fault protection

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized distributors as this part may be discontinued. Confirm package integrity and pin alignment for the 20-QSOP form factor before integration. Check for updated manufacturing notices regarding obsolescence or lifecycle changes. Ensure design compatibility with existing thermal management requirements for the specified operating temperature range.

Hot Swap Controllers Selection Notes

Select this controller when three-channel hot-swap functionality is required without internal switching elements. Consider the 20-QSOP package constraints for PCB layout space. Evaluate the need for automatic retry and fault timeout features against system recovery requirements. Verify that the 1V to 13.2V supply range aligns with the target bus voltages.

Hot Swap Controllers Part Context

This component belongs to the MAX5930/MAX5931 family of hot-swap controllers. It shares functional similarities with the MAX5930 but differs in packaging, utilizing a 20-QSOP instead of a 24-QSOP. Both devices support similar protection features and operate within comparable electrical parameters, offering flexibility in board design based on channel count and package availability.

Hot Swap Controllers Replacement Considerations

The MAX5930EEG+T serves as a pin-compatible alternative within the same family, offering identical functionality in a 24-QSOP package. Designers must account for the physical footprint difference when substituting components. No other direct substitutes are documented in the provided data.
