ISL6150IB

Hot Swap Controllers Overview

The ISL6150IB is a single-channel hot swap controller manufactured by Renesas Electronics Corporation, formerly Intersil. Designed for -48V and VoIP applications, it manages power insertion into backplanes without an internal switch. The device operates within a supply voltage range of 10V to 80V and supports industrial temperature ranges from -40°C to 85°C. It draws a typical supply current of 900 µA and is housed in an 8-SOIC package with a width of 3.90mm.

Hot Swap Controllers Feature Summary

• Integrated programmable circuit breaker functionality for precise current limiting
• Built-in overvoltage protection (OVP) and undervoltage lockout (UVLO) mechanisms
• Configurable fault timeout settings to manage transient events
• Latch-fault feature ensures safety during critical system errors

Hot Swap Controllers Applications

• -48V telecommunications infrastructure systems
• Voice over IP (VoIP) equipment power management
• Industrial backplane hot swap implementations
• Data center server power distribution units

Hot Swap Controllers Procurement Notes

Verify the specific suffix designation carefully, as the IB variant denotes industrial temperature ratings distinct from commercial grades. Confirm current availability status, as this component has been subject to discontinuation notices. Ensure compatibility with existing board layouts utilizing the standard 8-SOIC footprint before finalizing procurement decisions.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring robust protection for -48V architectures without integrating external pass transistors. Consider the latch-fault behavior if immediate shutdown upon error detection is preferred over auto-retry. Evaluate the 900 µA quiescent current against strict power budget constraints in always-on telecom environments.

Hot Swap Controllers Part Context

Originally developed by Intersil, this component is now part of the Renesas Electronics portfolio following the corporate acquisition. The ISL6150 series addresses the need for reliable power sequencing and protection in high-density electronic assemblies. It represents a legacy solution for older telecom designs transitioning to modern managed power architectures.

Hot Swap Controllers Replacement Considerations

Consult official product legacy documents for confirmed substitute part numbers. Verify pin-to-pin compatibility and electrical parameter equivalence with any proposed alternative controllers from the same manufacturer family.
