MAX5911ESA+ Equivalent & Substitute Parts

Part Overview

The MAX5911ESA+ is a hot swap controller manufactured by Analog Devices Inc./Maxim Integrated, designed for -48V applications requiring single-channel hot swap control with thermal limiting and programmable under-voltage lockout (UVLO) protection. This Active product is part of the Simple Swapper™ series and is available in 8-SOIC surface mount packaging. The device integrates an internal switch and operates across a supply voltage range of -65V to -16V with a maximum output current of 280mA.

Finding equivalent or substitute parts may be necessary due to supply chain constraints, inventory availability, or specific application requirements while maintaining functional and electrical compatibility.

• Supply Voltage Range: -65V to -16V compatibility
• Maximum Output Current: 280mA capability
• Package Type: 8-SOIC surface mount form factor
• Thermal Management: Thermal limit feature required
• Programmable Protection: UVLO (Under-Voltage Lockout) functionality
• Operating Temperature Range: -40°C to 85°C
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The MAX5911ESA+ serves as both the primary reference part and its direct equivalent. No alternative part numbers have been identified that maintain identical electrical specifications, channel configuration, and packaging requirements for this specific -48V hot swap control application.

Parameter Comparison

Engineering Selection Recommendations

The MAX5911ESA+ maintains Active product status with full ROHS3 compliance and REACH unaffected classification, ensuring regulatory alignment for current and future applications. The device's MSL rating of 1 (Unlimited) provides maximum flexibility for storage and handling without moisture sensitivity constraints.

For applications requiring -48V hot swap control with single-channel operation and integrated thermal protection, the MAX5911ESA+ represents the specified solution. The 8-SOIC package and -65V to -16V supply range are fixed requirements for mechanical and electrical compatibility within the target system architecture.

Frequently Asked Questions (FAQ)

Q: Can the MAX5911ESA+ be substituted with a different hot swap controller from another manufacturer?

A: Substitution requires matching all critical parameters: single-channel configuration, -48V application support, -65V to -16V supply voltage range, 280mA maximum output current, 8-SOIC package, integrated switch, thermal limit feature, and UVLO programmability. Alternative manufacturers' parts must meet these exact specifications.

Q: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC (0.154", 3.90mm Width) package is a surface mount form factor with fixed pin count and pitch. Any substitute part must use identical packaging to ensure PCB layout compatibility and assembly process alignment.

Q: Does the MAX5911ESA+ support positive voltage applications?

A: No. The MAX5911ESA+ is specifically designed for negative voltage applications (-48V systems) with a supply voltage range of -65V to -16V. It is not suitable for positive voltage hot swap control applications.

Q: What does the UVLO programmable feature provide?

A: Under-Voltage Lockout (UVLO) is a programmable protection mechanism that prevents the hot swap controller from operating when the supply voltage falls below a configured threshold, protecting downstream circuitry from improper operation during low-voltage conditions.

Q: Is the MAX5911ESA+ suitable for high-temperature industrial applications?

A: The operating temperature range is -40°C to 85°C. Applications requiring operation beyond 85°C require alternative components with extended temperature specifications.

Q: What is the MSL rating and why does it matter?

A: The Moisture Sensitivity Level (MSL) of 1 (Unlimited) indicates the component has no moisture sensitivity constraints. This allows indefinite storage without desiccant packaging or time-limited shelf life restrictions.
