Triple Linear Power Controller with ACPI Control Interface

The HIP6501A, paired with either the HIP6020 or HIP6021, simplifies the implementation of ACPI-compliant designs in microprocessor and computer applications. The IC integrates two linear controllers and a low-current pass transistor, as well as the monitoring and control functions into a 16-pin SOIC package.

Features
• Provides 3 ACPI-Controlled Voltages
    - 5V Active/Sleep (5VDUAL)
    - 3.3V Active/Sleep (3.3VDUAL)
    - 2.5V/3.3V Active/Sleep (2.5VMEM)
• Simple Control Design - No Compensation Required
• Excellent Output Voltage Regulation
    - 3.3VDUAL Output: ±2.0% Over Temperature; Sleep States Only
    - 2.5V/3.3V Output: ±2.0% Over Temperature; Both Operational States (3.3V setting in sleep only)
• Fixed Output Voltages Require No Precision External Resistors
• Small Size
    - Small External Component Count
• Selectable 2.5VMEM Output Voltage Via FAULT/MSEL Pin
    - 2.5V for RDRAM Memory
    - 3.3V for SDRAM Memory
• Under-Voltage Monitoring of All Outputs with Centralized FAULT Reporting
• Adjustable Soft-Start Function Eliminates 5VSB Perturbations
• Pb-Free Available (RoHS Compliant)
