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)
