ISL6504CB-T

Power Supply Controllers, Monitors Overview

The ISL6504CB-T 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, 1.2V VID Processor VID Circuitry, and 1.5VSB ICH4 Resume Well. It operates within a supply voltage range of 4.75V to 5.25V, draws 17 mA of supply current, and functions at temperatures from 0°C to 70°C.

Power Supply Controllers, Monitors Feature Summary

• Provides four distinct ACPI-controlled voltage planes including processor VID and resume well supplies
• Features excellent output voltage regulation with ±2.0% accuracy over temperature
• Includes centralized undervoltage monitoring and temperature shutdown protection

Power Supply Controllers, Monitors Applications

• ACPI-compliant power regulation for motherboards
• Microprocessor power management in computer systems
• PCI auxiliary and LAN power supply control

Power Supply Controllers, Monitors Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix 'CB-T' indicates tube packaging rather than tape and reel, as datasheets may list variations. Check RoHS compliance status carefully, as older batches may not meet current environmental standards. Validate lead times and availability given potential end-of-life status for legacy PMICs.

Power Supply Controllers, Monitors Selection Notes

Select this component for designs requiring integrated ACPI voltage sequencing and monitoring. Ensure compatibility with ATX power supply specifications for 5VSB and 3.3V inputs. Verify that the 16-SOIC package fits the PCB layout constraints. Consider thermal performance requirements for the linear regulators under maximum load conditions.

Power Supply Controllers, Monitors Part Context

The ISL6504 belongs to Renesas' family of power management ICs targeting desktop and server motherboard architectures. It complements voltage regulators by handling low-power rails and standby states efficiently. This series supports standard PC power states (S0-S5), enabling optimized power consumption during sleep and active modes.

Power Supply Controllers, Monitors Replacement Considerations

Check for direct pin-compatible replacements within the ISL6504A variant if S4/S5 behavior differs. Consult Renesas documentation for updated equivalents if the part is discontinued.
