Product details
Overview
HIP6503CBZ-T from Intersil is a multiple linear power controller IC designed for ACPI-compliant motherboard power management. It delivers five regulated voltages-1.8VSB, 2.5/3.3VMEM, 3.3VDUAL/3.3VSB, 2.5VCLK, and 5VDUAL-with ±2.0% output regulation over temperature, active/sleep state control via S3/S5 pins, and integrated undervoltage monitoring with centralized FAULT reporting. It operates in 0°C to 70°C ambient, uses external N-channel MOSFETs and NPN transistors for voltage switching, and targets microprocessor computer systems with ATX 3.3V/5V/5VSB/12V inputs.
For engineers reviewing the HIP6503CBZ-T datasheet, HIP6503CBZ-T pinout, HIP6503CBZ-T application, or HIP6503CBZ-T equivalent, this page provides verified technical context on its ACPI sleep-state sequencing (S0–S5), dual-mode 5VDUAL control (EN5VDL-gated), memory voltage selection (2.5V/3.3V via RSEL), fault latching behavior, and SOIC-20 package implementation with confirmed pin functions and drive capabilities.
Technical Context
The HIP6503CBZ-T implements three linear regulators (1.8VSB, 2.5/3.3VMEM, 2.5VCLK), one dual-mode switch controller (5VDUAL), and one linear regulator for 3.3VDUAL/3.3VSB-all coordinated by digital S3/S5 state inputs and EN5VDL enable logic. Its internal architecture includes five independent voltage monitors, a 10 μA soft-start current source, and deglitched 2 μs input filters on S3/S5 pins.
It supports two distinct operational modes: active (S0/S1/S2) where ATX 3.3V/5V supply outputs directly via external NMOS devices, and sleep (S3/S4/S5) where NPN or PMOS transistors deliver power from 5VSB or 12V rails. The 2.5VCLK regulator is disabled in all sleep states, while 1.8VSB remains active as long as 5VSB is present.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiple linear power controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP6502CBZ-T | Four-output variant (omits 2.5VCLK regulator); identical S3/S5 control, EN5VDL logic, and SOIC-20 package | Lacks dedicated clock chip supply - unsuitable where 2.5VCLK termination is required for processor or clock ICs | Select HIP6502CBZ-T only if 2.5VCLK is not needed and BOM cost reduction is prioritized over feature completeness |
| ISL6522CBZ-T | Successor generation with enhanced 5VDUAL current capability (15A vs. 10A typical), lower quiescent current (18 mA vs. 30 mA), and extended thermal shutdown threshold (165°C) | Requires updated layout for higher-current DLA/5VDLSB traces; supports newer chipset sleep-state timing tolerances | Choose ISL6522CBZ-T for new designs requiring higher 5VDUAL load current or improved thermal margin; not drop-in due to revised timing and drive strength |
Compared with HIP6502CBZ-T, the HIP6503CBZ-T adds a dedicated 2.5VCLK regulator for clock chip termination, enabling tighter noise isolation and eliminating need for external LDO. Compared with ISL6522CBZ-T, it offers proven legacy compatibility with older ATX PSUs and chipset timing but lacks higher-current drive and updated thermal thresholds.

FAQ
What is the function of the FAULT/MSEL pin on the HIP6503CBZ-T?
The FAULT/MSEL pin on the HIP6503CBZ-T serves a dual role: it reports system-level faults (undervoltage on any output or ATX input, or overtemperature >125°C) by pulling to 5VSB, and it selects memory voltage (2.5V for RDRAM or 3.3V for SDRAM) via an external resistor. An internal 40 μA current source develops a voltage across the resistor; comparison against a 200 mV reference latches the setting at POR or reset. HIP6503CBZ-T requires no capacitor on this pin to avoid false selection.
How does the HIP6503CBZ-T handle transitions between active (S0) and sleep (S3) states?
The HIP6503CBZ-T uses deglitched S3 and S5 inputs with 2 μs filtering and a 200 μs S3 delay timer to prevent noise-induced state errors. When S3 goes low, the timer starts; if S5 remains high at timeout, the IC enters S3 and switches 3.3VDUAL/3.3VSB and 5VDUAL to 5VSB-sourced paths using NPN/PMOS devices. HIP6503CBZ-T disables 2.5VCLK and maintains 1.8VSB. EN5VDL determines whether 5VDUAL stays active in S3.
Can the HIP6503CBZ-T operate without external pass transistors?
No, the HIP6503CBZ-T requires external pass devices for all five outputs: N-channel MOSFETs for active-state 3.3VDUAL/3.3VSB and 5VDUAL, NPN transistors for sleep-state regulation, and an external NPN for 2.5/3.3VMEM active regulation. Only the 1.8VSB and 2.5VCLK regulators are fully integrated with on-die pass elements. HIP6503CBZ-T's architecture relies on external transistors to handle high current and thermal dissipation beyond SOIC package limits.
What is the purpose of the SS (soft-start) pin on the HIP6503CBZ-T?
The SS pin on the HIP6503CBZ-T controls output voltage ramp rate via an external capacitor charged by a 10 μA internal current source. It enables two-stage soft-start: 1.8VSB and 3.3VDUAL/3.3VSB rise first, then after a 3 ms delay, remaining outputs follow. Pulling SS below 0.8 V forces full shutdown and resets FAULT latching. HIP6503CBZ-T uses this pin to prevent 5VSB rail collapse during cold boot and ensure controlled transitions between power states.
Is the HIP6503CBZ-T RoHS compliant and what does "Pb-Free Plus Anneal" mean?
Yes, the HIP6503CBZ-T is RoHS compliant under the "Pb-Free Plus Anneal" designation. This means it uses 100% matte tin plating, lead-free molding compound, and die attach materials, with an additional annealing step to prevent tin whisker formation. HIP6503CBZ-T is compatible with both SnPb and Pb-free solder reflow profiles and meets IPC/JEDEC J-STD-020 moisture sensitivity level requirements for SOIC packages.
