ISL6506BCBZA-T

Power Supply Controllers, Monitors Overview

The ISL6506BCBZA-T is a switching controller designed for ACPI-compliant power regulation in microprocessor and computer applications. It integrates control of the 5VDUAL and 3.3VDUAL rails within an 8-lead EPAD SOIC package. The device operates between 0°C and +70°C. It features selectable operating modes via S3 and S5 digital pins, utilizing an internal linear regulator for 3.3VDUAL generation during sleep states or an external N-Channel MOSFET for direct connection in active states. The ISL6506B variant provides a 2A current limit on its internal 3.3V LDO.

Power Supply Controllers, Monitors Feature Summary

• Integrates control for 5VDUAL and 3.3VDUAL rails into a compact 8-lead package
• Supports ACPI-compliant designs with selectable active and sleep output modes
• Generates 3.3VDUAL voltage plane internally during sleep states using ATX 5VSB
• Connects outputs directly to 3.3V input via external MOSFET in active states

Power Supply Controllers, Monitors Applications

• ACPI-compliant power regulation for motherboards
• Microprocessor power supply designs
• Computer application power management

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance status against the manufacturer's latest documentation. Confirm that the 'T' suffix corresponds to the required reel packaging format. Ensure the component matches the 8-lead SOIC-EP physical dimensions. Cross-reference the part number with official Renesas databases to confirm current production status and availability.

Power Supply Controllers, Monitors Selection Notes

Select this component for systems requiring integrated dual-rail control in ACPI environments. Choose the ISL6506B over the ISL6506A if a higher 2A current limit is required for the internal 3.3V LDO. Ensure the design accommodates the external N-Channel pass MOSFET for active state operation. Verify thermal requirements for the SOIC-EP package under maximum load conditions.

Power Supply Controllers, Monitors Part Context

This part belongs to the ISL6506B series from Renesas Electronics Corporation. It complements other power building blocks like voltage regulators in standard PC architectures. The series is specifically engineered to manage power states (S0 through S5) efficiently, reducing complexity in motherboard power distribution networks by combining multiple control functions into a single integrated circuit.

Power Supply Controllers, Monitors Replacement Considerations

The ISL6506ACB is a functionally similar alternative but lacks RoHS compliance and has different sleep mode characteristics for the 5VDUAL output. Verify pin compatibility and electrical specifications before substitution.
