The HIP6501A is a triple linear power controller with an ACPI control interface. It integrates two linear controllers and a low-current pass transistor, as well as monitoring and control functions. It simplifies the implementation of ACPI-compliant designs in microprocessor and computer applications.
The HIP6501A is a triple linear power controller designed for ACPI‑compliant microprocessor and computer systems. It integrates two linear regulators and a low‑current pass transistor to generate 3.3 V, 5 V, and 2.5/3.3 V memory rails from an ATX power supply, with dedicated pins for sleep‑state control and fault reporting.

| Operating Supply Current (I5SB) | 20 mA |
|---|---|
| Ambient Temperature Range | 0 °C to 70 °C |
| Junction Temperature Range | -0 °C to 125 °C |
| 3.3 V Linear Regulator Regulation | ±2.0 % |
| 5 V Dual Switch Controller Under‑Voltage Threshold | 3.750 V |
The HIP6501A supplies three ACPI‑controlled voltages: 3.3 V, 5 V, and a selectable 2.5 V or 3.3 V memory rail.
The device is specified for an ambient temperature range of 0 °C to 70 °C and a junction temperature range up to 125 °C.
The soft‑start begins when the 5VSB power‑on‑reset (POR) voltage exceeds its threshold, triggering an internal current source that charges an external capacitor to ramp the output voltages.
