ISL6506ACB

Power Supply Controllers, Monitors Overview

The ISL6506ACB is a multiple power controller designed for ACPI-compliant microprocessor and computer applications. It integrates control of the 5VDUAL and 3.3VDUAL rails within an 8-lead EPAD SOIC package. The device operates with a supply voltage range of 4.75V to 5.25V and draws a supply current of 3.6 mA. It supports operating temperatures from 0°C to 70°C. The component manages active and sleep states via digital control pins, utilizing external MOSFETs for efficient power delivery in active modes and internal linear regulation during sleep states.

Power Supply Controllers, Monitors Feature Summary

• Integrates control for 5VDUAL and 3.3VDUAL power rails into a compact package
• Supports selectable operating modes for active outputs or sleep outputs via digital control pins
• Generates the 3.3VDUAL voltage plane internally during sleep states using the 5VSB output
• Includes over-temperature shutdown protection

Power Supply Controllers, Monitors Applications

• ACPI-compliant power regulation for motherboards
• Microprocessor power management systems
• Computer application power supplies

Power Supply Controllers, Monitors Procurement Notes

Verify component authenticity as this part may be obsolete. Confirm RoHS compliance status, as some variants are non-compliant. Check for lead-free alternatives if environmental regulations require it. Ensure the 8-SOIC-EP package footprint matches the design. Validate that the specific suffix corresponds to the required electrical characteristics and pinout configuration.

Power Supply Controllers, Monitors Selection Notes

Select the ISL6506ACB for designs requiring integrated ACPI power rail management. Choose this model when minimizing external component count is critical. Consider the 8-lead SOIC-EP package for space-constrained motherboard layouts. Verify compatibility with the system's ATX power supply specifications for both active and sleep state operations.

Power Supply Controllers, Monitors Part Context

The ISL6506 series complements other power building blocks in ACPI-compliant designs. It functions alongside voltage regulators to manage dual voltage rails. The AC variant specifically manages the 5VDUAL output in sleep states differently than the B variant. It is part of the broader ISL6506 family intended for computer and microprocessor power applications.
