ISL6141IBZA

Hot Swap Controllers Overview

The ISL6141IBZA is a negative voltage hot plug controller designed for safe board insertion into live backplanes. It operates from -20V to -80V with an absolute maximum rating of -100V. The device limits inrush current by controlling an external N-channel pass transistor gate. It features programmable over-voltage, under-voltage, and current limit protections. An IntelliTrip electronic circuit breaker distinguishes between over-current and hard fault conditions, providing fast shutdown with a single retry. The unit is housed in an 8-SOIC package.

Hot Swap Controllers Feature Summary

• IntelliTrip electronic circuit breaker distinguishes between over-current and hard fault conditions
• Programmable inrush current limiting via external N-channel pass transistor control
• Integrated programmable over-voltage and under-voltage protection with hysteresis
• Active low PWRGD signal for direct power module enablement

Hot Swap Controllers Applications

• -48V telecommunications systems
• VoIP equipment
• Live backplane board insertion applications

Hot Swap Controllers Procurement Notes

Verify the specific suffix IBZA against the official datasheet to confirm pinout and packaging details. Confirm RoHS compliance status as indicated in the latest manufacturer documentation. Check for end-of-life notices or alternative part recommendations from Renesas Electronics before finalizing procurement plans.

Hot Swap Controllers Selection Notes

Select this component for negative voltage hot swap applications requiring precise inrush control. Ensure the external N-channel MOSFET matches the voltage and current requirements. Verify that the programmable thresholds align with the system's over-voltage and under-voltage protection needs.

Hot Swap Controllers Part Context

The ISL6141 belongs to the IntelliTrip family of hot plug controllers from Intersil, now part of Renesas Electronics. It is specifically engineered for -48V environments common in telecommunications. The companion device ISL6151 offers an active high PWRGD output instead of active low.

Hot Swap Controllers Replacement Considerations

The ISL6151 is a functional substitute with an active high PWRGD output. Verify pin compatibility and logic polarity differences when substituting.
