HIP6500BCB-T

Overview

The HIP6500BCB-T is a triple linear power controller with an ACPI control interface, designed for microprocessor and computer applications. It integrates two linear controllers and low-current pass transistors within a 16-pin SOIC package to simplify ACPI-compliant designs. The device manages multiple voltage planes, including generating the 3.3V DUAL plane from a 5VSB output during sleep states (S3, S4/S5) and switching in ATX outputs for active states (S0, S1). A third controller powers a 5V DUAL plane by selecting between ATX 5V and 5VSB based on system state. Operating modes are selectable via S3 and S5 pins, with additional logic control through EN3VDL and EN5VDL enabling pins.

Feature Summary

• Integrates dual linear controllers and monitoring functions into a compact 16-pin SOIC package
• Manages 3.3V DUAL and 5V DUAL voltage planes for both active and sleep power states
• Supports external N-Channel pass MOSFET configuration for enhanced current handling

Applications

• ACPI-compliant microprocessor power supply designs
• Computer systems requiring S3, S4, and S5 sleep state management
• PCI slot power distribution during low-power states

Procurement Notes

Verify the specific suffix 'CB' against the manufacturer's official datasheet to confirm pinout compatibility and thermal specifications. Ensure the component is sourced as a genuine Intersil or Renesas product to guarantee adherence to ACPI signaling standards. Cross-reference the manufacturing date code with current lifecycle status documentation to avoid obsolescence risks in long-term deployment.

Selection Notes

Select this component when designing systems that require integrated management of multiple linear voltage rails under ACPI control. It is suitable for applications needing precise switching between active and sleep power sources without discrete logic complexity. Consider the 16-pin SOIC package constraints for PCB layout and verify that the integrated pass transistor capabilities meet the load requirements for the 2.5V/3.3V memory power rail.

Part Context

This part belongs to the HIP6500 family of triple linear power controllers developed by Intersil. These devices are engineered to replace complex discrete solutions in PC architecture power management. The family focuses on simplifying the implementation of advanced power states required by modern processors, ensuring efficient power delivery during both high-performance and standby operations.

Replacement Considerations

Check for HIP6500A variants which may offer updated electrical characteristics or packaging options. Verify functional equivalence regarding the ACPI control interface and voltage regulation thresholds before substitution.
