ISL6151IBZA

Hot Swap Controllers Overview

The ISL6151IBZA is a single-channel negative voltage hot swap controller from the IntelliTrip series, designed for -48V VoIP applications. It operates within a supply voltage range of 20V to 80V and features an 8-SOIC surface-mount package. Key electrical parameters include a supply current of 2.4 mA and an operating temperature range of 0°C to 70°C. The device lacks an internal switch and includes programmable features such as current limiting, overvoltage protection (OVP), and under-voltage lockout (UVLO).

Hot Swap Controllers Feature Summary

• Integrates auto-retry functionality and fault timeout mechanisms for robust system recovery.
• Provides programmable current limiting, overvoltage protection, and under-voltage lockout capabilities.
• Designed specifically for safe insertion and removal in negative voltage environments.

Hot Swap Controllers Applications

• -48V telecommunications infrastructure
• VoIP equipment power systems
• Industrial control panels requiring hot-swap capability

Hot Swap Controllers Procurement Notes

Verify component authenticity due to Intersil's acquisition by Renesas Electronics. Confirm that the obsolete status does not impact long-term maintenance requirements. Check for RoHS3 compliance documentation if environmental regulations apply. Ensure the 8-SOIC package dimensions match the target PCB footprint before finalizing procurement decisions.

Hot Swap Controllers Selection Notes

Select this controller when designing circuits for negative voltage rails requiring precise thermal and electrical protection. Consider the absence of an internal switch, which necessitates an external MOSFET. Evaluate the 0°C to 70°C operating range against environmental conditions. Compare IntelliTrip series alternatives if higher channel counts or different voltage ranges are required.

Hot Swap Controllers Part Context

This component belongs to the IntelliTrip family of hot swap controllers manufactured by Intersil, now part of Renesas Electronics. The series focuses on protecting sensitive electronics during board insertion. As an obsolete part, it represents legacy design technology previously widely used in telecom power distribution systems.

Hot Swap Controllers Replacement Considerations

Consult Renesas Product Legacy Documents for officially confirmed substitute part numbers. Verify pin compatibility and feature parity with potential replacements before implementation.
