ISL6117CBZA

Hot Swap Controllers Overview

The ISL6117CBZA is a single-channel hot swap power controller designed for +3.3V control applications within the ISL61xx family. It operates with a supply voltage range of 9 V to 15 V and features an SOIC-8 package. The device includes hard-wired undervoltage monitoring at approximately 80% of the nominal rail voltage. Key electrical parameters include a minimum operating temperature of 0°C and a maximum of 85°C, compliant with RoHS standards.

Hot Swap Controllers Feature Summary

• Integrated hard-wired undervoltage monitoring threshold set at approximately 80% of the nominal voltage level
• Programmable overcurrent detection with adjustable regulation levels via external components
• Current regulation with time delay capability to latch-off during fault conditions
• Soft-start functionality to manage inrush current during module insertion

Hot Swap Controllers Applications

• +3.3V hot plug control applications
• Power distribution controllers for server backplanes
• PCI/PCI-X card slot protection
• Hot swap modules requiring controlled power-up sequences

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Renesas or Intersil distributors. Confirm the specific suffix matches the required package and temperature grade. Check for recent product discontinuation notices as legacy PMICs may have limited availability. Ensure ESD handling protocols are followed during storage and assembly.

Hot Swap Controllers Selection Notes

Select this part specifically for +3.3V rails; use ISL6115 for +12V, ISL6116 for +5V, or ISL6120 for +2.5V. This device lacks an internal charge pump, relying on the +12V bias voltage to enhance the N-channel pass FET. Verify that the system provides sufficient bias voltage for proper gate drive operation.

Hot Swap Controllers Part Context

Part of the ISL6115/6116/6117/6120 family of fully featured hot swap power controllers. Designed for high-side switch control in systems ranging from +2.5V to +12V. Manufactured by Intersil, now part of Renesas Electronics. Targets applications requiring robust power management and fault isolation.

Hot Swap Controllers Replacement Considerations

Direct functional equivalents within the same family include ISL6115CBZA (+12V), ISL6116CBZA (+5V), and ISL6120CBZA (+2.5V). Cross-referencing requires matching the target rail voltage and ensuring compatibility with the existing N-channel MOSFET gate drive requirements.
