ISL6504ACBN

Power Supply Controllers, Monitors Overview

The ISL6504ACBN is a multiple linear power controller with an ACPI control interface, designed for microprocessor and computer applications. It integrates three linear controllers/regulators, switching, monitoring, and control functions into a 16-pin wide-body SOIC package. The device provides four ACPI-controlled voltages: 5VDUAL USB/Keyboard/Mouse, 3.3VDUAL/3.3VSB PCI/Auxiliary/LAN, 1.2VVID Processor VID Circuitry, and 1.5VSB ICH4 Resume Well. It features excellent output voltage regulation of ±2.0% over temperature.

Power Supply Controllers, Monitors Feature Summary

• Integrates three linear controllers and switching functions for ACPI-compliant designs
• Provides four distinct ACPI-controlled voltage planes for system components
• Includes undervoltage monitoring with centralized fault reporting and temperature shutdown

Power Supply Controllers, Monitors Applications

• ACPI-Compliant Power Regulation for Motherboards
• Microprocessor Power Systems
• Computer Applications

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'CBN' against official Renesas documentation to confirm package type and RoHS status. Confirm current availability as older Intersil/Renesas PMICs may be discontinued or subject to last-time buys. Ensure compatibility with existing motherboard designs requiring ACPI S-states control.

Power Supply Controllers, Monitors Selection Notes

Select this component for systems requiring integrated ACPI voltage management. Compare the ISL6504 (5VDUAL shut down in S4/S5) versus ISL6504A variants based on sleep state requirements. Evaluate the 16-SOIC package constraints against PCB space limitations compared to QFN alternatives.

Power Supply Controllers, Monitors Part Context

Part of the ISL6504 family from Renesas (formerly Intersil), complementing voltage regulators in ACPI designs. The ACBN suffix typically denotes a specific commercial grade and tube packaging variant within the standard SOIC footprint.

Power Supply Controllers, Monitors Replacement Considerations

Check for direct pin-compatible replacements within the ISL6504 series. Verify if the ISL6504A variant meets design needs regarding 5VDUAL behavior in sleep states.
