Multiple Linear Power Controller with ACPI Control Interface

The HIP6502B complements either an HIP6020 or an HIP6021 in ACPI-compliant designs for microprocessor and computer applications. The IC integrates four linear controllers/regulators, switching, monitoring and control functions into a 20-pin SOIC package.

Features
• Provides 5 ACPI-Controlled Voltages
    - 5VDUAL USB/Keyboard/Mouse (Active/Sleep)
    - 3.3VDUAL/3.3VSB PCI/Auxiliary/LAN (Active/Sleep)
    - 2.5VMEM RDRAM (Active/Sleep)
    - 3.3VMEM SDRAM (Active/Sleep)
    - 2.5VCLK Clock/Processor Terminations (Active Only)
• Excellent Output Voltage Regulation
    - 3.3VDUAL/3.3VSB Output: ±2.0% Over Temperature; Sleep State Only
    - 2.5VMEM and 3.3VMEM Output: ±2.0% Over Temperature; Both Operational States (3.3VMEM in Sleep Only)
    - 2.5VCLK Output: ±2.0% Over Temperature
• Small Size
    - Very Low External Component Count
• Dual Memory Voltage Support Via MSEL Pin
    - 2.5V for RDRAM Memory
    - 3.3V for SDRAM Memory
    - Both 2.5V and 3.3V for Flexible Systems
• Under-Voltage Monitoring of All Outputs with Centralized FAULT Reporting and Temperature Shutdown

Applications
• Motherboard Power Regulation for ACPI-Compliant Computers
